svn+ssh://pythondev@svn.python.org/python/trunk ........ r73303 | ronald.oussoren | 2009-06-08 13:54:59 -0700 (Mon, 08 Jun 2009) | 11 lines This checkin adds a symlink to the lib directory of a framework install of Python (on OSX), and the end result of that is that the combination of ``python-config --ldflags`` and ``python-config --libs`` refers to an actually existing location. I've done this in preference to changing python-config to specify '-framework Python' for linking because that doesn't work when you have multiple versions of python installed (because '-framework Python' will always link to the 'Current' version of the framework, without a possibility to specify a specific version). ........
