cpan Catalyst::Runtime
cpan Package::Stash

You don't describe, how you tried to install?

There is many ways, i'd like to stick to package manager, so just:

sudo apt-get install libcatalyst-perl

Update: Your problem is certainly in mixed use of CPAN and Debian packages. You must get rid of one and you get it working.
