Undefined symbol "_glapi_Dispatch" on 6-STABLE/X.org 6.9.0 causes pymol failure

[Peter Lai]

I'm still having trouble with DRI on 6-STABLE using:

dri-6.4.1,1
Xorg-* 6.9.0
both built on Feb. 3 2006

Hardware: AGP Radeon 8500

glxinfo reports: direct rendering: Yes
glxgears reports: 11573 frames in 5.0 seconds = 2314.580 FPS

Error message is:
libGL: XF86DRIGetClientDriverName: 5.0.3 r200 (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/r200_dri.so
libGL error: dlopen /usr/X11R6/lib/modules/dri/r200_dri.so failed
(/usr/X11R6/lib/modules/dri/r200_dri.so: Undefined symbol
"_glapi_Dispatch")
libGL error: unable to find driver: r200_dri.so

And switches to Mesa Indirect

Application affected: pymol using libglut 6.4.1

Obviously, it cannot be a version sync issue, since I am using the
correctly distributed dri with the distributed Xorg. Of note is that
DRI requiring Dispatch  never worked on 5-STABLE with X.org 6.8.1
either. Any ideas?
