Normally with Anaconda I'd say just use the interpreter that comes with
it. The whole point of Anaconda as a package is that everything has been
built to be compatible. The minute you start trying to use its packages
with other modules/interpreters you are inviting pain.

I'd avoid that if at all possible. Rather try adding the opt folder to
your PYTHONPATH environment variable. sys.path uses that on setup.
But the simplest solution is just to use he Anaconda interpreter.
Don't worry if its a version or two behind current, Python
doesn't really change that much in releases.
