It looks like you don't have ATLAS ("Automatically Tuned Linear Algebra
Software") installed. The RHEL6 binaries are built against ATLAS as the
BLAS library (this is new with numpy 1.8.0; I'll update the instructions
& lsst-distrib script to reflect it).

Fixing this would be as easy as running 'yum install atlas' as root, but
given you don't have root permissions you'd need to install them from
source:

	http://math-atlas.sourceforge.net/

Also, make sure they're on your LD_LIBRARY_PATH.

PS: Note that now we're getting into hacking-around-the-binaries
territory that's really not recommended unless you know do these sorts
of things as a hobby... If there are more problems after this, you may
want to build from source.
