If I correctly understand you, one of the repos that I needed to install 
in my Add/Remove software (and yum) database was RPM Forge -- presumably 
for some application (or development environment) that I needed and that 
was not building easily from source.  Thank you for identifying the 
repository.  (Is there a list of which RPM comes from which repo?  That 
is, other than by prior knowledge and inspection, is there any 
clean/clear mechanism to identify .rfx. as RPM Forge, etc.?)

Thus, if I "deactivate" RPM Forge for now via the Add/Remove GUI, the 
update should work.  I will not be at my machine until Monday next, but 
I shall test this idea then.

Thanks,

Yasha
