Here is the beginning of the error from when i tried to emerge this package. It looks like CPAN::Meta and Parse::CPAN::Meta is required. >>> Emerging (18 of 21) perl-core/Module-Build-0.380.0 * Module-Build-0.3800.tar.gz SHA256 SHA512 WHIRLPOOL size ;-) ...

It turns out that I have virtual/perl-CPAN-Meta version 2.112.621 and virtual/perl-Parse-CPAN-Meta version 1.440.100-r2 installed. (The corresponding packages from perl-core are there too.) It seems like that the versions should be sufficient. I'll attach a build log.

never mind about this "bug". the problem was fixed by: perl-cleaner --all
