error loading shared lib

[Quentin Spencer <qspencer ieee org>]

I've never seen this before. I installed the latest octave and atlas on 
a devel machine and when I try to either start octave or even run ldd 
/usr/bin/octave, I get this:

octave: error while loading shared libraries: libblas.so.3: cannot 
enable executable stack as shared object requires: Permission denied

This works fine in FC-4, and used to work in devel. ATLAS was rebuilt 
after the upgrade to gcc 4.1, so I don't think that would cause it. Is 
it possible that further changes to gcc in the last month could have 
caused it? Any other ideas?
