test_blas failures

I am getting test_blas failures on 64bit Linux, but not 32bit Linux.
Is anyone else seeing this?  I would like to get these fixed before
releasing the 0.7.0b1.

These errors go away after building the ATLAS library from source
and linking to that (see previous message on test_arpack errors).
