Not only that, I doubt that this will work well unless
you now have two site-packages dirs (one in /usr/lib for
Python only extensions and one in /usr/lib64 for combined
Python and binary extensions).

Uhm, this is the function that Jeremy was patching - the problem
being that the "lib" part of the path is hard-coded into this
It doesn't parse the Makefile, BTW, and plat_specific only
adds site-packages to the returned directory - it doesn't
have anything to do with platform specific code.
The Makefile is the only place where Python itself can
look up how it was configured. It's easy to find:
distutils.sysconfig.parse_makefile(filename) then does the
rest. Or in one go: distutils.sysconfig.get_config_vars().
The interesting parts of the Makefile are these variables:
# Detailed destination directories
I guess we should change the install.py to use these
values instead of building its own little world of
What do you think ?
