Pip only does python stuff, of course, but that covers the must-haves and the strong recommendations. For the optionals, there's a way to define external requirements, and print a warning saying, "you should really consider installing this." I found a decent example of something that might be acceptable in the python module Shapely. See this gist for an example of what happens when you try to install it without a c library that makes it run faster:</div><div><br></div><div><a href="https://gist.github.com/beOn/4970435">https://gist.github.com/beOn/4970435</a></div><div><br></div><div>Would that kind of behavior be acceptable?

We do have a somewhat extensive testing to<br>guarantee that PyMVPA would still function nicely just with limited<br>functionality when those optional dependencies are present, but those<br>installations might feel crippled. So we are primarily orienting<br>ourselves for deployments on platforms with somewhat a guaranteed<br>coverage of those dependencies and sane upgrade/bug reporting<br>procedures, e.g. Debian-based (with our own NeuroDebian layer on top<br>;-) ), where we have a much better handle of things.
