No. The gcc-based Python 3.3.0 from python.org uses gcc to compile lxml.

10.7.5. If by "OSX Installer" you mean that for Python 3.3.0, then it 
was the 64-bit one from python.org.

compile its extensions, and weird things on particular operating systems 
related to that, are fair game for python-dev.
