Comment(by vbraun):
Atlas-3.8.3 does only provide a static lapack library, so cvxopt's
`lapack.so` statically linked it all:

Atlas-3.9.32 builds shared libraries and cvxopt now links against the
shared library.

In particular, ilaenv remains UNDefined in cvxopt `lapack.so` and atlas
`liblapack.so` and needs to be dynamically linked in from `libf77blas.so`.
I guess we should keep statically linking the static system-provided
lapack on Windows and OSX, or change cvxopt to use the C version
clapack_ilaenv (since it already links to `libcblas.so`)
