Suggestions?
I built PySparse on my Mac without problems, but I'm not on Mavericks. The compiler flags are managed by Numpy's distutils. Not all versions of gcc support the -arch flag. It seems that gcc-4.2, as installed by Homebrew, does. I would suggest that you either use that version of gcc, or temporarily remove gcc from your PATH so clang is used for compiling PySparse.

Let us know if that works.
