Yes, you could do that. Uninstall instructions for MacPorts are here: http://trac.macosforge.org/projects/macports/wiki/ FAQ#HowdoIremoveoruninstallMacPorts Before following those instructions, you may want to "sudo port -f uninstall installed" On Dec 20, 2007, at 00:55, Micheal Cooper wrote:

Since I don't have anything of worth in the db yet, can I just uninstall everything via Ports, remove /usr/local, and then reinstall from zero?

I went through several attempts to install a django dev environment, and in the process I installed different versions of python from dmg and macports, uninstalled, etc. In the end, I uninstalled everything and then did: `sudo port install py25-psycopg2` which also installed postgresql81 and python25, then I did 'sudo port install postgresql81-server subversion' after which I should be ready to go, but I am not.

When I run 'python manage.py runserver' in my django project directory, I get: raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured : Error loading psycopg2 module: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: /usr/local/pgsql/lib/libpq.4.dylib Referenced from: /Library/Frameworks/Python.framework/Versions/ 2.5/lib/python2.5/site-packages/psycopg2/_psycopg.so

Danger, Will Robinson: /usr/local? The python25 port has inadvertently been linked against the PostgreSQL library found in your /usr/local directory. This is why we recommend not having anything in /usr/local. Stuff there frequently conflicts with MacPorts ports. Please move /usr/local elsewhere, for example /usr/ local-off, then rebuild any ports (such as python25) that have inadvertently linked against things in /usr/local. Once you're sure everything works, and once you've replaced anything in /usr/local-off with ports, remove /usr/local-off.

Using `sudo locate libpq.4.dylib` gives me: /opt/local/lib/postgresql81/libpq.4.dylib /opt/local/var/macports/software/postgresql81/8.1.10_0+darwin_8/ opt/ local/lib/postgresql81/libpq.4.dylib

I would rather have the system set up to rely on MacPorts so that I can update/ upgrade with ease. I did install psycopg2 from a dmg before starting over and installing through MacPorts, so I can only assume that the system is looking for the old psycopg2 and not finding the one installed by MacPorts.

I have not created anything yet, and this is only a dev environment I am trying to set up, so I would be happy to delete a lot of stuff and start from scratch again, but since I uninstalled everything and then reinstalled with MacPorts twice, I seem to be missing someone.

Please advice, and thank you.
