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 (This should rebuild out-of-date dependencies.)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.
