There is a potential problem here in the backports.org policy of not
accepting packages that can be installed from squeeze.

There is a caveat when installing from CPAN on Debian-based
distribution. Debian's perl is so configured that cpan installs stuff
in /usr/local and that tree is before /usr/{share,lib}/perl5 in @INC.
So once you install from CPAN, that version will take precedence over
the one installed via a debian package, even if you upgrade the
distribution.
