Ryan,

it seems you try to run scipy with different version of numpy than it 
was compiled with. did you try removing existing installation and 
rebuilding all sources?

Anyway missing umfpack would not cause all those errors.

libamd.a has nothing to do with the amd processors - it it a library (a 
part of umfpack-related package) for ordering a sparse matrix prior to 
Cholesky factorization (http://www.cise.ufl.edu/research/sparse/amd/) 
and you do not need it if you do not use umfpack.
