"Personal" term in Apple license

[Alberto Luaces <aluaces@udc.es>]

Hello,

I have updated the debian/copyright file of the package
"openscenegraph".

When writing the file, a line caught my attention, because it mentions
that the license is "personal" and "non-exclusive":

https://anonscm.debian.org/cgit/pkg-osg/pkg-osg.git/tree/debian/copyright?h=debian-osg-3.2&id=0e3adbf30d2b1b02710513ac22c9711f5e9d8cad#n417

The files covered by this license are not even used for Debian (they are
part of the MacOS code).  Should I take them out of the sources?

Please Cc:, as I am not subscribed.

Thanks,

Alberto
