They actually install in a python installed from python.org, not system

.so is the usual extension for python extensions on mac os x

How did you run nose ?

Setting up the MKL is a bit tedious, but essentially, you need to
create a site.cfg in the source tree that looks as follows:

library_dirs = "where the libraries are"
include_dirs = "where the headers are"
libpack_libs = mkl_lapack95
mkl_libs = mkl_intel,mkl_intel_thread, mkl_core, mkl_p4m, mkl_p4p

and (that's the undocumented/buggy part), set ATLAS=1 to disable accelerate.
