Removing perl module installed with cpanm

That's quite experimental for the moment being, but now cpanm supports an uninstall option. From MetaCpan :

-U, --uninstall

EXPERIMENTAL: Uninstalls the modules. Will remove the distribution files from your library path using the .packlist file. When used with -l or -L, only the files under the local::lib directory will be removed. NOTE: If you have the "dual-life" module in multiple locations (i.e. site_perl and perl library path, with perl 5.12 or later), only the files in site_perl will be deleted. If the distribution has bin scripts and man, they will be kept in case the core installation still references that, although there's no guarantee that the script will continue working as expected with the older version of .pm files.

Try App::pmuninstall
