so, for the really out of date...

I am running a Mac, v 10.6.8

It's some animal, I really don't follow this, like a lion (I think.)

Now, this mac is the only machine I let touch the internet.  So obviously I have to make git work here.  I have gnu gcc installed.  Is their source code I can compile (see, I'm not only paranoid but old. not a great combination, I am learning...)
