I had recently updated my copy of R to 2.15.1 and ended up needing to reinstall some libraries, including rgl.

install.packages(“rgl”, repos=”http://R-Forge.R-project.org”, configure.args=”–disable-cocoa –with-gl-includes=/opt/local/include –with-gl-libs=/opt/local/lib –with-x”)
Once installed, rgl can make cool figures, like this:
