As stated in the log, you have restricted permissions: {{{ 74 configure:2423: /opt/local/bin/python2.7 -c import sys # split strings by '.' and convert to numeric. Append some zeros # because we need at least 4 digits for the hex conversion. # map returns an iterator in Python 3.0 and a list in 2.x minver = list(map(int, '2.5'.split('.'))) + [0, 0, 0] minverhex = 0 # xrange is not present in Python 3.0 and range returns an iterator for i in list(range(0, 4)): minverhex = (minverhex << 8) + minver[i] sys.exit(sys.hexversion < minverhex) 75 ./configure: line 2424: /opt/local/bin/python2.7: Permission denied }}} Look at the permissions of all those relevant files to see why you're getting EPERM. Eg: {{{ $ ls -ld /opt /opt/local /opt/local/bin /opt/local/bin/python2.7 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 drwxr-xr-x 5 root wheel 170 Jan 24 00:58 /opt drwxr-xr-x 13 root admin 442 Apr 11 02:56 /opt/local -rwxr-xr-x 1 root wheel 33728 Apr 11 02:42 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 drwxr-xr-x 2695 root admin 91630 Jun 3 02:09 /opt/local/bin lrwxr-xr-x 1 root admin 73 Apr 11 02:42 /opt/local/bin/python2.7 -> /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 }}} By "sudo is not being passed down to the spawned or forked processes" do you mean that root permissions are not being used to build? Yes, that is correct and intentional. Projects are built as the macports role account user and then installed as root. -- Ticket URL: <https://trac.macports.org/ticket/51547#comment:9> MacPorts <https://www.macports.org/> Ports system for OS X
