hi august,

answer this one private: how are you? i hope well.

sounds convincing. what you mean is to issue the "opengl-update nvidia" 
command. i could swear i did so, yet it might still be that i did it 
while in X and then the wrong lib would've been already in use - or 
even the command might have failed silently. i will have a look at the 
libGL myself.

rebooting did not solve anything. i would be glad if you have a look 
(into bash_history :) on thursday.

the strange thing is that e.g. glxgears works - only gem fails. i've 
got no other opengl app installed.

now that last sentence _is_ much help because it gives confidence.

one more question: did you activate DRI in the kernel (i use 2.6.9)? 
gentoo docs say "no" while nvidia docs (used to) say "yes".
