"ValueError: Namespace PangoAttrCast not available" when trying to run Labyrinth (gtk3 branch)

[mknepper]

This is what I get when I run labyrinth:

ValueError: Namespace PangoAttrCast not available

Debian testing is the distro I'm using for running this.

This was one of the bits missing from Pango, so I made a tiny little module to expose the necessary functionality through GObject introspection. You'll need that built and installed to run the gtk3 branch at present (I said it was a WIP, right? 😉 ).

Since then, the necessary pieces got added to Pango, so if you've got Pango >= 1.50, it should be possible to get rid of PangoAttrCast again.
