Don't worry, it's not really well documented. Create a file called site.cfg in
the root source directory. There's an example site.cfg.example there.
Unfortunately, it's pretty sparse at the moment. Now, I'm not terribly familiar
with the MKL, so I don't know what libraries do what, but here is my guess at
the appropriate things you will need in site.cfg:
[DEFAULT]
library_dirs=/home/tdennist/lib:/some/other/path/perhaps
include_dirs=/home/tdennist/include
[blas_opt]
libraries=whatever_the_mkl_blas_lib_is,mkl_ia32,mkl,guide
[lapack_opt]
libraries=mkl_lapack,mkl_lapack32,mkl_ia32,mkl,guide
There's some more documentation in numpy/distutils/system_info.py .
