Fixed dependencies for precise32.box - Ubuntu 12 LTS

In reply of issue #1 

First at all thanks for the help on getting abit started on puppet ! :) 

Fixed dependencies for a precise32 (Ubuntu 12) box Vagrant.

I am curious if these adjustment work for you aswell :)

Also added require => Package(gettext) on 'configure'. The ensure_packages method seemed out of order (make, g++ were installed, but then mono started downloading and configuring.. after that the package gettext was installed.. this made mono fail, because it has a dependency on gettext. Same applies for libgdiplus)
