More space for julia-deps PPA

Hello there, I noticed that I'm over my 2GB limit for space in my julia-deps PPA. This PPA is a collection of all the dependencies needed to run Julia (http://julialang.org) on precise, quantal, and raring. Because Julia's development pace is quite fast, she often requires libraries that are newer than the libraries provided from the ubuntu main repositories, and so I have put together this PPA to gather all the needed extra packages together.

Thank you for Launchpad!
