I see the issue, but that is not exactly a ShareDir proble. ShareDir gets you to the base directory, after that, its all up to you. Its definitely in Alien::Base domain.

I think Alien::wxWidgets handles it in a reasonable way, though it necessitates Wx::Perl::Packager, you can't get by with File::ShareDir::PAR

'package' => 'Alien::wxWidgets::Config::msw_2_9_0_uni_gcc_3_4',
'package' => 'Alien::wxWidgets::Config::msw_2_8_10_uni_gcc_3_4',
'package' => 'Alien::wxWidgets::Config::msw_2_8_12_uni_gcc_3_4',
C:\perl\site\5.14.1\lib\Alien\wxWidgets

Does it need to be a module? NO
