I addressed a psycopg question to this list before, and I am grateful for the guidance that I received. The recommendation was that I start over, so I removed all my ports and then MacPorts altogether, and then I made double-plus-sure that all installations of postgresql and psycopg2 were removed from the system. I then reinstalled everything, using MacPorts defaults and following the rules with no modifications or customizations. Though I finally got my database users, etc. down and my django up and running, when it came time to use the Python-Postgresql functionality, I got the following: ------ netadminmac:~/Documents/djangotests/mysite mcooper$ python manage.py syncdb Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/__init__.py", line 272, in execute_manager utility.execute() File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/__init__.py", line 219, in execute self.fetch_command(subcommand).run_from_argv( self.argv) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/base.py", line 72, in run_from_argv self.execute(*args, **options.__dict__) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/base.py", line 85, in execute self.validate() File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/base.py", line 112, in validate num_errors = get_validation_errors(s, app) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/core/management/validation.py", line 22, in get_validation_errors from django.db import models, connection File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/db/__init__.py", line 17, in <module> backend = __import__('%s%s.base' % (_import_path, settings.DATABASE_ENGINE ), {}, {}, ['']) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 15, in <module> raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named psycopg2 ------ So it seems that Postgresql and Python cannot talk, but here are my ports: ------ netadminmac:~/Documents/djangotests/mysite mcooper$ sudo port installed Password: The following ports are currently installed: apr @1.2.12_0 (active) apr-util @1.2.12_0 (active) bison @2.3_1 (active) db44 @4.4.20_1+darwin_8 (active) expat @2.0.1_0 (active) gawk @ 3.1.5_2 (active) gettext @0.17_2 (active) libiconv @1.12_0+darwin_8 (active) m4 @1.4.10_1 (active) ncurses @5.6_0+darwin_8 (active) ncursesw @5.6_0+darwin_8 (active) neon @0.26.4_0 (active) openssl @0.9.8g_0 (active) postgresql81 @8.1.10_0 (active) postgresql81-server @8.1.10_0 (active) py25-psycopg2 @2.0.5.1_0 (active) python25 @2.5.1_4+darwin_8 (active) readline @5.2.007_0 (active) sqlite3 @3.5.4_0+darwin_8 (active) subversion @1.4.5_0 (active) zlib @1.2.3_1 (active) ------ Here is a list of locations of psycopg: ------ netadminmac:~/Documents/djangotests/mysite mcooper$ locate psycopg /opt/local/lib/python2.5/site-packages/psycopg2 ... /opt/local/var/macports/distfiles/python/psycopg2-2.0.5.1.tar.gz ... /opt/local/var/macports/software/py25-psycopg2 /opt/local/var/macports/software/py25-psycopg2/2.0.5.1_0 ... /opt/local/var/macports/software/py25-psycopg2/2.0.5.1_0/opt/local/lib/python2.5 /opt/local/var/macports/software/py25-psycopg2/2.0.5.1_0/opt/local/lib/python2.5/site-packages ------ Here is my ~/.profile: ------ netadminmac:~ mcooper$ cat .profile stty erase export LC_CTYPE=en_US.UTF-8 # Setting the path for MacPorts. export PATH=/opt/local/bin:/opt/local/sbin:$PATH # Setting PATH for MacPython 2.5 export PATH=/Library/Frameworks/Python.framework/Versions/Current/bin:$PATH export DISPLAY=:0.0 export PATH=$PATH:/opt/local/lib/postgresql81/bin alias pgstart="sudo su postgres81 -c 'pg_ctl -D /Users/DB/postgresql -l /Users/DB/postgresql/logfile start'" alias pgstop="sudo su postgres81 -c 'pg_ctl -D /Users/DB/postgresql stop -m fast'" alias pgstatus="sudo su postgres81 -c 'pg_ctl status -D /Users/DB/postgresql'" ------ And here is my attempt to figure out which competing versions of Python may be installed.

If that is the case, would it solve my problem to just point to the MacPorts version in my ~/.profile? I was going to try this, but the /opt/local/bin/python2.5 is a file, not a directory, so it looks like they are not equal. Could someone please help me? I am trying to learn django and python, and I would like to do it on the Mac. However, I have to tell you that the install on my Windows machine was a no-brainer series of "Next" clicks and some posgresql tinkerin at the end. This django install has really made me question the move to Mac. -- Miyazaki, Japan (GMT+9, no DST)
