mpatch requires python and the python distutils to install.

To install in the default locations (/usr or /usr/local usually):
$ python setup.py install --force

To install in your home directory (~/bin and ~/lib, actually), run:

$ python setup.py install --home=${HOME} --force
$ export PYTHONPATH=${HOME}/lib/python  # (or lib64/ on some systems)
$ export PATH=${HOME}/bin:$PATH         # add these to your .bashrc
