Bug 205881: devel/py-pip: Add a warning against installing into system
site-packages with pip!
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205881



--- Description ---
If pip is used to install software into system's site-packages, python packages
installed from ports later will conflict with that, if, for example, a common
dependency has been previously installed with pip and later is pulled in
through ports.

Need to add a warning to pip not to install packages into system's
site-packages, in form of a pkg-message.
