Create a (non-admin) standalone GCC/G++

I have a Mac Mini at home, with my own administrator account. My school provides MacBook Airs. I have XCode installed on the Mini, but I only use the command line extensions-- GCC, G++, etc. I don't have admin access on the Air. I would like to have GCC and G++ on the air, and would be fine with using it in the format "./g++ [arguments]" or making a bash script ran that (unless arguments are used, the output file is always named "a.out"-- even if that already exists.) and was used like this "./build fileName.cpp". I just want to have it on the Air. Both are 10.9 Mavericks. Even a location of the executable on the hard drive would help.

Please note that .pkg files (such as the command line tools download available from apple) require administrator privileges to install.
