Rather than building MonoDevelop from source, it is much better to follow the directions on the MonoDevelop website.

This guide should only be followed if you are both running Ubuntu 14.04 and you need MonoDevelop version 5.

If you're on Ubuntu 14.04 and you only need MonoDevelop 4, you can run sudo apt-get install monodevelop.

If you're on a version of Ubuntu newer than 14.04, you can install MonoDevelop 5 just by running sudo apt-get install monodevelop.

If you're on Ubuntu 14.04 and need version 5, run the following commands, one after the other.

sudo apt-get update
sudo apt-get install monodevelop
