[Answer]-ImportError: No Module named picklefield.fields (Yep pip install says it is there)

You should be able install via:

/[your python install directory]/bin/pip install django-picklefield

If you do this directly instead of a general pip call to install django-picklefield, that will ensure that it is installed on the correct version of Python.

Based on your description my best guess is that you have multiple versions of Python installed, and that your install/uninstall is happening on the wrong one.
