Interesting though this is, why are we trying to bootstrap the entire rebuild? Perl 5.14 is sufficiently compatible with 5.12 that we can continue to provide perl(:MODULE_COMPAT_5.12.*) in perl-5.14.1 rpm until the rebuild is (nearly) complete and only need to worry about bootstrapping the arch-specific stuff (a much smaller problem set with no circular deps that affected my rebuild in mock). Once all the arch-specific stuff is rebuilt, all of the noarch packages should just work (except those with real failures due to new features - mostly regex stringification messing up tests). -- Iain. -- Fedora Extras Perl SIG http://www.fedoraproject.org/wiki/Extras/SIGs/Perl perl-devel mailing list perl-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/perl-devel
