AFAIK we have had problems like this before with various bits of Xorg
(iirc) needing the sources of other bits to build.

The "usual" solution for this, is to give a package a -source subpackage,
which contains the extracted sources (and installs them under
/usr/src

So I think the best way to handle this is to package gluegen, and include
gluegen's sources as a gluegen-source subpackage, and then make jogl
BuildRequire gluegen-source.
