[Gtk2hs-devel] Hidden modules?

[Matt A. <ar...@rp...>]

If I try to build Clutterhs with recent versions of Gtk2hs, I get build errors such as:
    Could not find module `Graphics.UI.Gtk.Types':
      it is a hidden module in the package `gtk-0.12.0'
      Use -v to see a list of the files searched for.

This didn't used to happen. I need access to the various type modules for Pango types, and for ClutterGtk. What can I do?
