title: Package dependencies from a local pypi repository
body: <p>i have googled for an answer but i did not find anything really matching my needs (but i might be wrong).</p>
  
  <p>We have a local Pypi repository that we need to use for our dependencies.</p>
  
  <p>I am trying to use <code>dependency_links</code>, but apparently that's deprecated, plus, this is not working.</p>
  
  <p>I have found lots of confusing posts about github.com repositories, which are not what i need to achieve (that's pretty easy); my problem is using another pypi index-url for our packages.</p>
  
  <p>Thanks</p>
