[MonoDevelop] Gtk# project with parallel mono environment

[Nicholas Frechette]

Posting here this in case someone has this issue again.

Following this guide helped:
http://www.centriment.com/2009/04/01/building-mono-24-from-source-on-ubuntu-810/
The main thing I can see that was missing is that most of the gnome dev
packages are required, specially glade#. Without glade#, gtk# projects are
not generated properly and the designer doesn't work.

However, libxul-dev is broken atm on ubuntu so whatever depends on it might
not work (thankfully i don't require it).

All fixed now.
