Perhaps you could have raised a RT ticket for this issue.

Perhaps then either myself or Jos would have been able to investigate the issue. It is only because I happened to being checking perlmonks today that I spotted this.

You hit the nail on the head, it is the distributions that have package names that are slightly unusual that parse_module has a problem with. In the vast majority of cases it can make an educated guess and get it right.

CPANPLUS' module tree is exactly that, a tree of modules, which includes the name of the package that that module is contained in. Creating a mapping back the other way as well, ie. PACKAGE -> MODULE, is going to add more memory usage for the indexes.

That said, there may be a way. I'm digging further.

But please, do raise that ticket, so I don't forget.

Updated:

Found a possible solution which I will endeavour to roll into the next release. In the meantime this should work for those pesky edge-cases:

use strict;
use warnings;
use CPANPLUS::Backend;

my $cb = CPANPLUS::Backend->new();

my $string = shift || die;

my $mod;

unless ( $mod = $cb->parse_module( module => $string ) ) {
   ($mod) = grep { $_->package_name eq $string } 
                 $cb->search( type => 'package', allow => [ qr/^\Q$str
+ing\E/ ], );
}

print $mod->name, ' ', $mod->package, "\n" if $mod;
