You can install this fork with pip:
$ pip install -e git+git://github.com/cburgmer/surf.git#egg=surf
Sadly PIP can't find "sub-packages" due to bug http://bitbucket.org/ianb/pip/issue/2/allow-installing-packages-with-non-root. So you need to install the plugins manually.
Git to SVN
It's not too easy to extract a patch to apply to SVN but the following should work. Choose the commit you want to create a patch for and run:
$ git clone git://github.com/cburgmer/surf.git $ cd surf $ git checkout -b mydiff origin/surfrdf $ git cherry-pick COMMIT_SHA1_ID $ wget https://github.com/cburgmer/surf/raw/master/git-svn-diff.sh $ sh git-svn-diff.sh
