This was due to an oversight on my end. I used gentoo's package manager to 
completely remove atlas/blas/lapack, and afterwards verified that every 
instance of /usr/lib/libatlas.* had been removed. I did not check that 
libblas.* and liblapack.* had been removed, but I should have. Unfortunately, 
a few broken soft links remained, which scipy found and tried to build 
against. After removing those links, I was able to build scipy_core. How 
embarrassing. I'm sorry for the noise.
