OK, many thanks for tracking this down.  I have a more generic question 
though, now that you're familiar with my approach: do you agree with it?  What 
I concluded was that the RPM 'arch' flags were not sufficient to address the 
needs of something like ATLAS, since they lump everything since a Pentium Pro 
into i686, and are similarly coarse-grained for Athlon.  That's why I decided 
to use the hack of using the release tag to encode an additional architecture 
flag according to ATLAS conventions, and take advantage of yum's new $YUM<N> 
variables to load packages without conflicts.

I realize it's a bit hackish, but I don't see a better solution.  Do you agree 
with me, or do you think this can be solved in a cleaner way?

If you agree, then I'll make the changes you suggested and we can use this to 
quickly use/test/update the ATLAS binaries Pearu so kindly provides (I should 
explicitly thank Pearu for this, it really is a great service to all of us).

Cheers,
