[New-bugs-announce] [issue14188] Sharing site-packages between Apply and python.org builds breaks extensions

[Barry Alan Scott]

New submission from Barry Alan Scott <barry-scott at users.sourceforge.net>:

I'm testing on Mac OS X 10.7.3

http://bugs.python.org/issue4865 added
/Library/Python/2.7/site-packages
to the path for python.org built 2.7.

This will work for .py files but .so cannot be shared.
pysvn will SEGV python.org 2.7 when it is built against apple 2.7.

Because /Library/Python/2.7/site-packages is before
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages it is not possible to work around by install two binary kits.

To reproduce:

Install pysvn 1.7.6 for python.org
Then run python.org 2.7 and import pysvn. This will work.

Install pysvn 1.7.6 for Apple python. python.org 2.7 import pysvn is now broken.
