I haven't checked for a while, but I don't think that installing the ppm package for Bundle::Gnome2 gets you any closer to installing Gnome2 on Windows.
Bundle::Gnome2 is a pure perl package that probably builds fine under ActiveState's automated ppm build process, but doesn't provide any of the guts that are needed to successfully install Gnome2 on Windows.
To the OP:
My
sisyphusion ppm repo does provide Gtk2 Windows binaries.
Does that help ? Precisely which Gtk2 module is needed ?
I've been unable to get very far wrt Gnome2 because I couldn't get one of the pre-requisite C libraries to build. (Perhaps someone else has done better - it has probably been a year since I re-visited that particular problem.)
Cheers,
Rob
