How To Compile Cog VM on Ubuntu 12.10 64bit

Disclaimer: I used these instructions and the ubuntu_mvm script to build a Newspeak VM. However, this should be easily adaptable to a Squeak Cog build. It probably works on other modern linux systems, but I haven't tested any other distro. Please tell me if it does (not) work for you.
