Looks like el4 ships with a provided version of this package: el4: perl-Parse-Yapp-1.05-32.src.rpm epel has: epel: perl-Parse-Yapp-1.05-36.el4.1.src.rpm We should never replace a "core" rhel package. We should dead.package the epel4 version of this package and remove it from the repos...
How did I missed that... Everything should be done now.
It should be removed from the repo now.
