Yes. We still have a patch for two things:
1. fix setup.py script to look for libraries in correct (lib64) prefixes, and
2. fix values returned from sysconfig, to reflect that python resides in lib64

"$prefix/lib" is hardcoded in many places. Lib64 is probably not going away anytime soon, so it would be nice if this was solved once and for all ;)
The good thing is that with sysconfig, we don't have to do much beyond teaching sysconfig about the right values.

To reiterate, our current solution is to introduce "sys.lib" (and "sys.arch", but that is never used anymore) that is either "lib" or "lib64", and use this in place of the string "lib" wherever appropriate. We find the value for sys.lib through configure magic.
