You should be able to do that in one go with:

  $ sudo pip uninstall scikit-learn

Then you can build inplace the compiled extensions of scikit-learn git
clone with:

  $ cd scikit-learn
  $ python setup.py build_ext --inplace

And install a symlink to your dev folder with:

  $ sudo pip install -e .

Now whenever you "import sklearn" in a python script it should pick up
the dev version from your git clone. To update it to get the latest
changes, just do:

  $ git pull origin master
  $ python setup.py build_ext --inplace  # only required if ".c" or
".cpp" files have been updated
