install.packages("rgl") and dyn.load("PATH.TO.rgl.so/rgl.so") work on my 
Gentoo box. (I can't run library(rgl) from home without X so I cannot say 
what else works.)

Along the lines of Dirk's suggestions, recent R-ebuilds use

CDEPEND="dev-lang/perl
         >=dev-libs/libpcre-7.3
         app-arch/bzip2
         virtual/blas
         virtual/ghostscript
         readline? ( sys-libs/readline )
         jpeg? ( media-libs/jpeg )
         png? ( media-libs/libpng )
         lapack? ( virtual/lapack )
         tk? ( dev-lang/tk )
         X? ( x11-libs/libXmu x11-misc/xdg-utils )"

and of course all of THEIR dependencies.

But I'd just try

 	emerge -pD R

to see what would get rebuilt. (This should rebuild out-of-date 
dependencies.)

If you installed R using emerge and anything besides R would get rebuilt, 
then run 'emerge -D R'.

If you followed the R Installation and Admin guide to install R (as I do 
as I hate waiting months for the latest release to be deemed stable enough 
to be unmasked), then emerge everything listed by 'emerge -pD R' up to R 
itself, reinstall R, and try again.

FWIW,

 	equery depgraph R | less

will allow you to check all the R dependencies, but there are over 
1000, so this is probably a bit much.

HTH,

Chuck
