Shout if I'm wrong, but I say, you can use the OpenGL libraries, but you have
to install the relevant patches. Note that these patches are thought to be
stable but not necessarily guaranteed to be supported when you find bugs. ;-)

        Patch 154 First Open GL patch.

        Patch 918 New improved Open GL patch, supercedes 154, but
pre-reqs
                        Patch 1116, which is an XFS roll-up.

For what its worth, I run with these patches :-

        426 uipc 3 panic
        738 hinv command for ASO/SAMZ, new IBM tape drives, & PCMCIA
        797 race condition with uipc_vnlist[] causes system panic
        865 fixes xfsdump large extent bug
        917 EFS Filesystem roll-up patch (efs.a for XFS)
        918 RE OpenGL Extensions, Aux Buffers, and Bug Fix Rollup
        996 XFS rollup patch
        1115 5.3 Development Headers.
        1116 5.3 XFSData Management Interface (DMI) roll up and libc patch
        1120 XLV rollup including multiple IO4's

Someone else might wish to confirm / deny, but I believe you will get better
performance from recompiling with Iris GL, however, if you stick to Open GL
libraries then you will be IR ready ;-)
