When I emerge mozilla-firefox, the emerge fails with "XML::Parser perl module is required"
Note that Perl is not something I have emerged - if it exists on my system it's been pulled as a dependency.
Note also that I do not have very many things in world at the moment.
Steps to Reproduce:
1. emerge mozilla-firefox
XML::Parser perl module is required
