Yes, if you want.  As long as the offending rpm's are out of the yum 
repositories.  I believe I have gone through all of the plain Scientific Linux 
repositories.  If someone finds that I missed one of the offending rpm's, 
please let me know.

When RedHat started doing this, they made sure that their packages has the 
exact same names as RedHat's.  I'm not sure of the details, if they did it by 
hand or already had their scripts ready to do the %{dist} tag.  They have some 
Fedora people, and I know Fedora has done %{dist} for a long time, so maybe 
they already had it setup correctly before RedHat even changed anything.
This is one case where they did it right, and we did it wrong.
