Well, my manager came back, and he's got me using virtenv. Having read
about it, I like it.  Oh, and the issue with the system numpy in
site-packages was that, for some reason, it was *not* world-readable.
Fixed that.

So, I'm working on trying to install scipy in the virtenv... and for
unknown reasons, it simply can't find the system libs. I did this before
the last attempt to
export LAPACK=/usr/lib64/liblapack.so.3
export BLAS=/usr/lib64/libblas.so.3
and just added export LD_LIBRARY_PATH=/usr/lib64
Still can't find them.

Clues on this one?
