glNormal3f and glTexCoordPointer are both OpenGL entry points used by 
rgl, so the messages are indicating a linking problem.  But I don't know 
enough about Linux to recognize whether that's because of something 
wrong with Gentoo or what you did, or something wrong with the rgl 
configure script.
