For what it is worth, the Debian r-cran-rgl packages uses these Build-Depends
which may or may not map into similar Gentoo packages:
Build-Depends: debhelper (>= 5.0.0), r-base-dev (>= 2.6.2), cdbs, \
libgl1-mesa-dev | libgl-dev, libglu1-mesa-dev | libglu-dev, \
libpng12-dev, libx11-dev, libxt-dev, x-dev
So try looking for libgl and libglu, possibly in their mesa implementations.
