Yeah, that kind of workaround could solve the problem for larger 
installations.
My point with this is, that yum (and other software updating tools) 
should always try to do the best they can, with what they've got. If 
it's missing parts of a header, clearly that package cannot be updated. 
But that's no reason to skip other updates that do not have a problem. 
Same thing for deps. If a package is missing a dep, we cannot update 
that package, period. But all the other updates that have no problems 
should still not be ignored.
