Hi
Niko Tyni found to that Math-Random-Mt fails to build from source with
Perl 5.12.0 configured to use long doubles. Please see [1] in the
Debian Bugtracker for his report, attached too below.
This seems to show up too from CPAN testers, for some reports, eg [2].

This package fails to build on amd64 with perl 5.12.0-1 from experimental:

This almost certainly happens because 5.12.0-1 is configured to use
long doubles (-Duselongdouble). CPAN test reports support this.
