py-* ports falsely appearing as deps

[rank1seeker at gmail.com]

Like plaque, in many installed ports after issuing: # make missing
--
devel/py-pytest-capturelog
devel/py-pytest-timeout
devel/py-pytest-xdist
devel/py-virtualenv
devel/py-scripttest
devel/py-pretend
devel/py-freezegun
devel/py-dateutil
--

I can confirm that for; x11-drivers/xf86-video-ati, x11-servers/xorg-server, x11-toolkits/gtk20, ...
Those will also list as deps for ports, even they aren't port's deps and aren't built.
