I wonder if you built the lapack libraries with the -fPIC flag though?
 I've attached my build scripts for atlas, the include make file for
the lapack libraries, and a python script to combine them - I am
wondering if you need the modified include make file, which should
somehow end up in your LAPACK directory as make.inc (see the
build_full.py script).
