warning "already imported from" when trying to import

[Patrickyp]

When I try to import nanomsg in python 2.7 I get the following:

$ import nanomsg

/usr/local/lib/python2.7/dist-packages/nanomsg-1.0-py2.7-linux-armv7l.egg/_nanomsg_cpy.py:3: UserWarning: Module _nanomsg_cpy was already imported from /usr/local/lib/python2.7/dist-packages/nanomsg-1.0-py2.7-linux-armv7l.egg/_nanomsg_cpy.pyc, but /home/pi/gitlibs/nanomsg-python is being added to sys.path

I installed using sudo python setup.py install. Any way to fix this warning?
