A PPA is an individual's repository.  They're used to dristribute more up-to-date versions of software than the distro maintainer.  A good example of a PPA is postgresql.  They test their new builds on Ubuntu, but Ubuntu only tests one of their builds every 6 months.  By adding the Postgresql PPA, you can get the most up-to-date stuff in a more timely fashion.

Another good use for a PPA is for non x86-64 architectures (which the raspberry pi is).  Adding a PPA is the same operation as adding a repository.  apt-add-repository is the command for Ubuntu I believe.

I say this because I've attempted to compile things on a Pi 2, and it's an overnight wait.

Mike,

What load are you running on your Pi?

I have the B and it comes loaded with 2.7.3, which is, for all practical purposes the same, I would think.

This link addresses the issue in the Ubuntu environment and may be informative.

if you are running the early Pi, perhaps yo might want to consider getting a second SD chip and experimenting with a newer version of Raspbian, or at least give yourself a spare load that you can mess up without grief.

my little raspberry pi needs at the least pyhon2.7.10. If it understood what a ppa is this would be a simple matter but as fate would have it I need to compile from source. Will doing that screw up anything ?
