Just enough in this case; thanks.

The problem appears to be in the Makefile for gtk.

$pkg info -r python-2.7_2,2


/usr/ports/lang/python/Makefile specifies

I did the following:

removed the python: dependency in gtk20 Makefile,
then make deinstall and make reinstall.
That fixes the issue in openshot with the missing libmp3lame library.

I'm not sure what the proper way to modify the gtk20 Makefile is to fix this,
so I'll just file a bug and let someone with more knowledge do it right.

Thanks again,
