Once you have done that, you can also symlink the binary from each into
your regular PATH (e.g., ln -s ~/git/1.8.0/bin/git ~/bin/git.v1.8) to
make it easy to switch between them. The installed exec-path is baked in
at compile-time, so it finds the correct git sub-programs properly.

I keep a couple dozen built versions of git around like this for quick
regression testing of bugs we see on the list.
