There is something wrong with your build environment. How did you set up
your compilers? Using the Xcode command line tools or did you get your
compilers from a third-party source?

Does cython import successfully? If so, what's the output of
cython.__file__? cython.__version?

I think this message about not uninstalling cython is related to
virtualenvs. Do you use virtualenvs?

How did you set up your Python environment? You mentioned anaconda Python,
what happens if you install cython using conda?

Finally, OSX 10.6 is getting a bit long in the tooth (for example, conda no
longer supports it), maybe that's part of the issue?
