Not strange at all. The python.org Python 2.6 (which is installed to
/Library/Frameworks/Python.framework) is deliberately built to be
compatible with OS X 10.3.9 through 10.6 and, as such, requires gcc-4.0
and the 10.4u SDK. The latter is included in the 10.6 Xcode
distribution as a separate package but is not installed by default; to
build a Python C extension module for that Python, you need to go back
to the Xcode installer for Snow Leopard (or download a new one from
Apple) and do a custom installation of that SDK.
