To my knowledge, the only system dealing with non-perl dependencies is the CPAN.pm plugin CPAN::Plugin::Sysdeps. The Gnome2::Canvas definitions look like this:
https://github.com/eserte/cpan-plugin-sysdeps/blob/1ec83eeb34cf7333cd919bcf3d768fd820077bc0/lib/CPAN/Plugin/Sysdeps/Mapping.pm#L1327-L1334
The other possibility would be to create Alien::* modules for the external deps, but this may easily get quite tedious.

Best is to close after release.
