The F-9 packages of perl-mogilefs-server have modules in "perl 5.8.8" paths, which are not found by F-9's perl 5.10.0. The package therefore needs rebuilding for perl 5.10.0. There was a mass rebuild of perl packages late in the F-9 development period but this package missed out on it, possibly because it is missing some perl version "module compat" dependencies (the main package has one but the subpackages, which also install into versioned perl module directories don't) and hence didn't have broken deps when perl was upgraded to 5.10.0. Also, the bugzilla component for this package is perl-MogileFS-Server but the package in cvs is perl-mogilefs-server, which seems a bit odd.
Created attachment 310587 [details] Patch to add perl(:MODULE_COMPAT... dependencies to subpackages
Thanks for noticing this Paul. I'll have a look later this week.
Fixed in 2.17-6
