Comment 3 for bug 32042

I didn't start using Ubuntu until Dapper, so I'm not aware of the original Ubuntu package that would have stored this data.

However, given how useful it's been to me, I scrounged around for a while and found the Debian package that contains the manpages (along with some debug libraries):

http://packages.debian.org/stable/libdevel/xlibmesa-gl-dev

Manually unpacking and copying the manpages over has really made me happy :). Not sure if that's helpful for building the final package, but it's certainly useful for me in the interim. I didn't see any licensing info in the pages themselves; but since they're in debian stable it seems like there shouldn't be too much of a conflict.
