[Koha] problem with Storable.pm version

Hi I'm trying to upgrade from koha 3 to koha 3.2 on debian etch and have run ./koha_perl_deps.pl -u -m and it is telling me that Storable is 2.18 and needs to be 2.21 I tried downloading the source and installing manually but now I have /usr/lib/perl/5.8.8/Storable.pm being 2.21 and /usr/local/lib/perl/5.8.8/Storable.pm being 2.18 but the check still says I've only got version 2.18 and need to upgrade how do I get the check to see the newer version? Or is there a better/more correct way to install Storable.pm? Any help will be appreciated Bob
