A couple of guesses here.

Does 'glxgears' work or give you a similar error message??

Obviously, if it breaks, your system is the issue.

You can get some sense of what is going on by setting

 	export LD_DEBUG_OUTPUT=tmp.debug
 	export LD_DEBUG=all

running something - like glxgears or R (invoking library(rgl))

then

 	grep glNormal3f tmp.debug.*

For one of my gentoo systems running an ati video card, I get this after 
glxgears

cberry at coyote ~ $ grep glNormal3f tmp.debug.*
       6846:     symbol=glNormal3f;  lookup in file=glxgears [0]
       6846:     symbol=glNormal3f;  lookup in file=/usr/lib/libglut.so.3 [0]
       6846:     symbol=glNormal3f;  lookup in file=/usr/lib/libGLU.so.1 [0]
       6846:     symbol=glNormal3f;  lookup in file=//usr/lib64/opengl/ati/lib/libGL.so.1 [0]
       6864:      binding file glxgears [0] to 
//usr/lib64/opengl/ati/lib/libGL.so.1 [0]: 
normal symbol `glNormal3f'


and after R <return> library(rgl) I get many more lines, but again 
ending with this long (wrapped) line"

 	6857:  binding file /home/cberry/lib.loc/rgl/libs/rgl.so [0] to
 	//usr/lib64/opengl/ati/lib/libGL.so.1 [0]: normal symbol `glNormal3f'


Maybe this helps:

Have you tried opengl-update?
