Recent changes in the main Perl package's handling of the module directory structure have resulted in shared files being installed incorrectly, e.. under /blib in the buildroot rather than where they should go. See bug 557015 for more detail. Padre leverages install_share() extensively, and the spec file simply removes them rather than installing them in the correct place. This does not seem conducive to the proper functioning of Padre :) I believe the proper resolution here would be to correct the issue in the main Perl package; this bug should remain open to track the issue in this package until it has been rebuilt with everything installed as upstream intended.
I thought there was mistake in Padre package, but now I'm aware of the problem in perl of Module::Build. Anyway all files are installed and application is functional. I've tested it. Files are "installed" twice into /blib and /usr/share. I'll do removal of 'rm -rf' as soon as building of packages is fixed.
