OS X: Portable Git (also install multiple versions of Git)

I am currently trying to install several versions of Git on OS X for testing. After downloading the OS X installation package from git-scm.com (which installs on /usr/local/git), I move it to another location, for example. ~/git-1.7.11.1or ~/git-1.8.1. Unfortunately, Git does not like this move:

$ ~/git-1.7.11.1/bin/git fetch
fatal: Unable to find remote helper for 'https'

or even worse:

$ ~/git-1.7.11.1/bin/git pull
git: 'pull' is not a git command. See 'git --help'.

Did you mean this?
        shell

When I set the path, it also does not work:

$ export PATH=~/git-1.7.11.1/bin:$PATH
$ which git
/Users/xxx/git-1.7.11.1/bin/git
$ git pull
git: 'pull' is not a git command. See 'git --help'.

Did you mean this?
        shell

Is there something I need to change in Git packages to make them portable (e.g. working in every place)?
