If you need to use pip rather than relying on system packages, then I'd
strongly recommend doing so in conjunction with virtualenv.  That way
you don't have to drop things into /usr/local, and if you find that some
other thing you want to run needs a conflicting set of Python packages
(after all, you've had to do this job once, so why not a second time?)
then they can have environments that don't interfere with each other.
