codepy.toolchain.ToolchainGuessError: unknown compiler

[bradddd]

I'm trying to install this on OS X. When I try to run the tests script, I'm getting the below:

Traceback (most recent call last):
  File "tests/gmm_test.py", line 4, in <module>
    from gmm_specializer.gmm import GMM

    raise ToolchainGuessError("unknown compiler")
codepy.toolchain.ToolchainGuessError: unknown compiler

Anyone have any idea which setting I'm missing?
