The current version (0.076-1) of perl-CPANPLUS needs Module::Pluggable for the
initial configuration.  After just installing perl-CPANPLUS, I get following
error message when running "cpanp".

It looks like Module::Pluggable is loaded dynamically which is why it isn't
included in the automatic requires list.  My impression is that this is only
needed for initial configuration.  If CPANPLUS is already configured, it works
fine.  Since Module::Pluggable is available in Extras, it would probably be best
to add an explicit Requires.
