XQuartz and xorg-server are the same software, except that xorg-server is several years more up to date. There would be no advantage to installing XQuartz instead of xorg-server.

If the rgl R library is something you are installing outside of MacPorts, then perhaps it is looking specifically for XQuartz in its install location of /opt/X11. You may need to inform it that you have installed it to the MacPorts prefix /opt/local instead.
