BUG: ~/pydistutils.cfg can break python installs

[micktwomey@…]

When installing darwinports onto a new mac I encountered a problem with the python24 port. I would get the following error when starting up python:

totoro:~ mick$ sudo port install python24 ... totoro:~ mick$ python Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] Python 2.4.3 (#1, Jul 10 2006, 11:28:23) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information.

Looking in /opt/local/lib/python2.4 the python libraries and modules were completely missing.

port contents python24 showed that the majority of the python install wound up in my ~/Library/Python/2.4. This lead me to suspect my ~/.pydistutils.cfg as the cause:

[easy_install] site_dirs = ~/Library/Python/2.4/site-packages script_dir = ~/Applications/bin

[install] install_lib = ~/Library/Python/$py_version_short/site-packages install_scripts = ~/Applications/bin

It appears this was overriding the distutils configuration during the python build.

Simply moving my .pydistutils.cfg out of the way and running "sudo port -f install python24" fixed the problem.

It would be good to ignore any pydistutils.cfg files during the port build.

python25 is also broken.

The python portgroups do ${python.bin} setup.py install --prefix=${prefix} --root=${destroot} for the destroot phase. I guess ~/.pydistutils.cfg must override the options given on the command line. If that is how it's meant to work, is this really our bug?

This is being worked on upstream: ​http://bugs.python.org/issue1180

Will attach a tarball with a few files:

• diff to the Portfile
• a new files/patch-Lib-distutils-dist.py.diff (from issue 1180 mentioned above) to add the --no-user-cfg option
• an updated files/patch-Makefile.pre.in.diff to use the new --no-user-cfg

Since issue 1180 notes only 2.6, I've created this so python 2.5 at least can make use of it as well.

python25 has been updated in r42997 (maintainer timeout).

[jmroot (Joshua Root)]

Added --no-user-cfg to the build and destroot commands in the python25 portgroup in r45192. Shall we call this fixed, or do we want to backport to python24?

--no-user-cfg is in python25, pytho26, and python30.
I do not think there is a compelling reason to add it to python24.
I vote that this ticket should be closed.

Agreed, 2.5 has been the default for a while now (this ticket is old hence references to 2.4), so unless someone has a really compelling argument for it, closed.
