Please upgraded perl-Module-Install to latest upstream version (1.10 currently) in rawhide (1.06 currently).
There are some changes in dependencies and I do not want to understand what is and is not optional, so I will do the the rebase in F22 only not to doom F21.
I cannot build it because latest perl-Module-Build removed some modules: DEBUG util.py:283: Error: Package: perl-Module-ScanDeps-1.14-1.fc22.noarch (build) DEBUG util.py:283: Requires: perl(Module::Build::ModuleInfo)
