A module has been installed and Python is able to import it in the dist-packages folder but not anywhere else

Question

I am working on harvest API for Python. When I run Python on terminal in /usr/local/lib/python2.7/dist-packages.

It is able to import harvest. But when I run the same command in any other folder it isn't able to recognize the same and throws ImportError.

The module I am using is in (got this from inspect.getfile).

'/usr/local/lib/python2.7/dist-packages/python_harvest_redux-3.1.1-py2.7.egg/harvest/harvest.pyc'

How can I go about this?
