Dear R users,

This is a follow-up of a recent discussion on building rgl on Gentoo
Linux. Please read bellow.

I have entirely updated my system using "emerge -tva -DNu world", also
meaning that I switched to R version 2.6.2. I have rebuilt all
packages broken by this update using "revdep-rebuild -i -tva -X". Just
to make sure, afterwards I have also "emerge -tva mesa
xf86-video-i810". My mesa USE flags look like this:
localhost liviu # eix mesa
media-libs/mesa
     Installed versions:  7.0.2(15:23:17 09/04/08)(video_cards_i810
-debug -doc -kernel_FreeBSD -motif -nptl -pic [..])

Building and loading rgl has only switched the error message:
> dyn.load("/usr/lib/R/library/rgl/libs/rgl.so")
Error in dyn.load("/usr/lib/R/library/rgl/libs/rgl.so") :
  unable to load shared library '/usr/lib/R/library/rgl/libs/rgl.so':
  /usr/lib/R/library/rgl/libs/rgl.so: undefined symbol: glNormal3f

Previously it was: "undefined symbol: glTexCoordPointer".

Does this look like an rgl or a Gentoo Linux issue? Would any of the
disabled mesa USE flags be worth enabling?

Thank you in advance,
Liviu
