dev-haskell/gtk-0.12.4-r1 build log

As I mentioned in bug #507390, the latest stable dev-haskell/gtk-0.12.4-r1 won't build against cairo-0.12.5* because of "Ambiguous occurence `Region'" in Graphics.UI.Gtk.Cairo.

Looks like this breaks because cairo-0.12.5.0/Graphics/Rendering/Cairo/Types.chs exports 'Region' only if x11-libs/cairo is new enough:

43 #if CAIRO_CHECK_VERSION(1,10,0)
44   , RectangleInt(..)
45   , RegionOverlap(..)
46   , Region(..), withRegion, mkRegion
47 #endif

and now stable is up to x11-libs/cairo-1.12.16.  dev-haskell/cairo-0.12.4 doesn't have this conditional export.

Downgrading to cairo-0.12.4-r1 before building gtk-0.12.4-r1 works.  Unkeywording dev-haskell/{pango,glib,gio,gtk}-0.12.5* also works.

Should be resolved by newer stable version in bug #524790

Yep, works now.  Thanks.
