I'm afraid that's a bit beyond my expertise - I haven't seen that
particular error before. The only thing I can suggest is to check
again against the instructions on the wiki, and remember it can be
quite sensitive to details... One thing I thought was check the order
of the libs listed in your site.cfg:
atlas_libs = lapack, f77blas, cblas, atlas

I know that changing the order there can result in errors similar to
the one your seeing.
