Okay, it looks like ATLAS's multithreaded libraries are being picked up before
the single-threaded libraries. Try the following site.cfg:

[atlas]
library_dirs = /usr/local/lib/atlas
libraries = lapack, f77blas, cblas, atlas

If that doesn't work, copy the single-threaded libraries named above to
somewhere else (like /home/sgong/dev/dist/lib/), and use the following site.cfg:

[atlas]
library_dirs = /home/sgong/dev/dist/lib
libraries = lapack, f77blas, cblas, atlas

You may have to run ranlib on the libraries after you copy them.
