If it's a dependency declared in your setup.py, you can do something like this:

     dependency_links=['http://path/to/svn/repos#egg=Foo-dev'],
     install_requires=['Foo>=1.2,==dev'],

in your setup() call, to depend on version 1.2 or greater of Foo; the ==dev 
and the #egg=Foo-dev will allow it to be found via SVN.

See also these two manual sections that document the use of ==dev and #egg=:
