[Distutils] Building Python extension modules on OS X without distutils

[Tim Smith]

I wrote a post about a problem Homebrew sees pretty often on OS X
where projects link extension modules with -lpython (either explicitly
or because they trust python-config --ldflags). If you see somebody
doing this, please point them to this post and invite them to use
-undefined dynamic_lookup instead, so that the Python symbols are
resolved at import time.
