We got this problem too, for x86_64 arch only.
It's turned out that 5.2 x86_64 have both i386 & x86_64
perl arch rpms in the x86_64 repository. But i386 perl just
absent in x86_64 5.3 release.
  So, my guess ia remove i386 perl from the machine w/ x86_64
arch and try again. Sorry, We does not finished upgrade here,
so it's a guesses only solution.
