Is it?  Do you have X11 installed (from Xquartz on your OS)?  The 
standard rgl (like the standard Tk) is an X11 application.  If you do 
have Xquartz installed, try launching manually first, in case launchd is 
somehow broken on your system.  And check that DISPLAY is not set.

X11 rgl works fine on both my 10.8.2 systems.

As far as I know aglrgl.so needs a Quartz event loop running, and that 
is what R.app provides.

The strange part is, if the package loads fine within the R GUI app.  Loading in verbose mode shows the successful load in R.app as:
