Package: libmath-random-mt-perl
Version: 1.10-1
Severity: important
User: debian-perl at lists.debian.org
Usertags: perl-5.12-transition

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.
