...which makes lxml pretty unhappy. Why is that?

I'm not lxml's maintainer, I'd suggest asking Stefan...

The binary was created on an older release of OSX where gcc is a valid compiler choice. Distutils should still pick clang when it detects that gcc is actually llvm-gcc though, doesn't it do that on your system?

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

BTW. Which OSX release are you using? And which variant of the OSX installer?

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.

P.S. Isn't this a question for python-list?

I think questions about compiling python and how python chooses to compile its extensions, and weird things on particular operating systems related to that, are fair game for python-dev.

cheers,

Chris
