and currently Gtk3 ...

... which is inaccessible to perl on Windows, afaik.

The perl Gtk3 module has a dependency upon the Glib::Object::Introspection module which, in turn needs the gobject-introspection library.
Last time I checked, I couldn't find any Windows binaries for gobject-introspection and trying to build the library myself is the most frustrating experience I have *ever* had as regards building a single library - due mainly to the involvement (and inadequacy) of python in the build process.

I'd be interested to hear if anyone has better success than I had when trying to install Glib::Object::Introspection on Windows.
Or maybe someone knows of gobject-introspection binaries for Windows ? (I've given up on even checking.)

Cheers,
Rob
