python distribute dependency_links to local git repositories

Question

Lets say I have following 2 packages:

/srv/share/python/core
/srv/share/python/package1

which package1 has dependency on core both have remote git repositories in:

/srv/git/core.git
/srv/git/package1.git

How do I define setup() in package1's setup.py to install core from /srv/git/core.git automatically while installing package1?

Answer 1

Finally sorted it out, major problem was distribute was out of date as it couldn't recognise git+file ran "pip install -I distribute" to update distribute to latest 0.6.35

then within setup()

 install_requires = ['core'],
 dependency_links = ['git+file:///srv/git/core.git/#egg=core'],
