It looks like cpan installed it, though its dependancies didn't install cleanly.
Makefile.PL fails to require() it, so thinks its not installed.
Try installing Data::Visitor - and check cpan's output for errors.
If that still doesn't work, force install the listed modules:
    cpan i -f Catalyst::Plugin::ConfigLoader

I know in the past cpan would continue to install modules, even if
their prereqs failed - I can't remember if this was fixed by a cpan
upgrade or a cpan config setting.
