Okay, for all you people out there who have had trouble. I just went through the entire setup process with a fresh install of Ubuntu Server 12.0.4 and here are my findings.
You need to remember to install all dependencies, namely these ones in particular.
apt-get install php5-mysqlnd php5-curl build-essential libboost-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev git
Additionally you need to remember to set file permissions, own your public folders with the Apache file group, www-data, and make your logging directory writable, for testing purposes I just 777'd all the files and folders, never do that on a production site. See MPOS setup for more information.
chown www-data public/templates/compile public/templates/cache logs
Also remember to update to the latest version of all things with apt-get update/upgrade.
This should clear up any errors you're having, if you experience any other errors, well let me know as usual.
And thanks to those who found bugs for this project and reported them.
