using Pygsl with GCC 4.0 in Python

I am trying to install pygsl using latest version of GCC, i.e.:

$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5659)

I get the error:

$ sudo python setup.py build
numpy

Any idea what might be causing this? thanks.

Although gcc-4.2 is installed, you see that the build is using gcc-4.0 -- confusing. Where's the "gcc-4.0" coming from ? Maybe the setup.py, or ~/.pydistutils.cfg, or export CC-gcc-4.0 or ... just guessing, I don't have pygsl. Can you get gcc-4.0 out of the way, as described in SO setting-gcc-4-2-as-the-default-compiler-on-mac-os-x-leopard ?
