[Numpy-discussion] numpy + MKL problems

None of that-this is why it has been so frustrating!

Only thing I did was remove the folders in the ./build directory in order
to get a cleaner slate, and just changed a couple libraries in site.cfg,
and got the error, and it persisted even when I went back to the libraries
I had given it when I got it to work.  So I am really confused as to what
could have caused the issue to start with.

Anyways, it seems okay now-I had to add mkl_lapack to the library list.
 Everything isn't 100% yet, but I can now work with it.
