You shouldn't have to provide a separate binary.  I've not moved to the
latest version on Linux, but that's not been a problem with using an nVidia
card.

Over a year ago I installed dx on a RH6.2 system with a Matrox G200 and
used the SGI OpenGL from the OpenDX download site.  It worked fine with h/w
rendering, but performance was poor.  I then replaced the Matrox card with
an nVidia Quadro card.  This used the nv driver that comes with XFree86
3.3.x.  It ran with h/w rendering, but not well.  I then installed the
drivers from nvidia.com, which replaces OpenGL with a version that
leverages the hardware as has been discussed on the mailgroup.  It works
quite well.  I've since upgraded to RH 7.0 and XFree86 4.1.0 and the latest
nVidia drivers.  It was all transparent to DX -- the same version from the
initial installation.

So if you build OpenDX the way you suggest with SGI OpenGL and then
run on a system with the Nvidia setup, do you get the benefit of the
true hardware rendering or should I provide a binary for both Nvidia
hardware and non-Nvidia hardware?
