...that you have noticed, so far.

That's unusual, as we have probably all had issues at some point with some
package install, that we have had to remove and reinstall to fix, if we have
installed and upgraded enough packages over a long enough period of time.
Setup is normally reliable, but networks sometimes are not, and problems
occasionally occur syncing some package mirror directories, or downloading the
packages.

The question is do you have libgtk*-devel installed and what is the *current*
package status of that and the other prerequisites?
