Quick license question for teapot

[Misha Koshelev]

Dear All:

Sorry to bother - apparently Owen Rudge has done quite a bit of basic
texture work, so I will await his patches to start my texture work.

As for teapot, Henri recommends looking at freeglut. I know wine is:
http://www.winehq.org/license
GPL 2.1

Freeglut is
"freeglut is released under the X-Consortium license."
http://freeglut.sourceforge.net/index.php#download

Just wanted to double check if these are compatible.

Thx
Misha
