This is an extension to scie.nti.st » Hosting Git repositories, The Easy (and Secure) Way by Garry Dolley describing how to install gitosis in completely non-root environments.

Adapt this for your login shell, if you're not using bash.

export PATH=$PATH:$HOME/opt/bin
export PYTHONPATH=$PYTHONPATH:$HOME/opt/lib/python2.5/site-packages/

Source it:

. ~/.bashrc

Only do this if setuptools isn't installed already and you can't install it as root!

Find the latest version of setuptools at http://pypi.python.org/pypi/setuptools.

mkdir -p ~/opt/lib/python2.5/site-packages/
wget http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c9-py2.5.egg
sh setuptools-0.6c9-py2.5.egg --prefix="$HOME/opt"

git clone git://eagain.net/gitosis.git
cd gitosis
python setup.py install --prefix="$HOME/opt"
