Thanks for the suggestion.  Do you have any Mac users doing this?

I installed XCode (to get the Mac native X11 on Lion [10.7.5]),
installed XQuarz, as well as the latest Macports to get/install GTK.

Running the app w/ this env. var now yields the following error:

Could not set X locale modifiers
Gtk not found (missing LD_LIBRARY_PATH to libgtk-x11-2.0.so.0?), using
built-in colorscheme

Unhandled Exception: System.EntryPointNotFoundException:
  at (wrapper managed-to-native)
System.Drawing.GDIPlus:GdipCreateFromXDrawable_linux (intptr,intptr,intptr&)
  at System.Drawing.Graphics.FromXDrawable (IntPtr drawable, IntPtr
display) [0x00000] in <filename unknown>:0

The error message "Gtk not found" combined with the
EntryPointNotFoundException in GdipCreateFromXDrawable_linux() leads me
to believe that flag either causes Mono to not look at the correct
LD_LIBRARY_PATH or the right filename (as macports uses

Any suggestions on overcoming this issue?
