Mono

I recently had a bit of an adventure trying to get the latest MonoDevelop installed. There are some undocumented dependencies that took me a while to figure out, so hopefully this will save someone some time:

1 - Build and install mono-addins

Get the package from http://monodevelop.com/Download

Then use the normal build and install method:
./configure
make
sudo make install

2 - Install the following packages using synaptic

These are required dependencies for building gtk-sharp WITH glade support.

libgnome2-dev
libgnomecanvas2-dev
libgnomeui-dev
libgnomeprint2.2-dev
