Neely,

as Duncan was saying R-SIG-Mac is a better place to discuss it.

This usually means that you have an old package for R 2.2.0 and you  
are trying to use it in R 2.3.0. *)

AFAIR rgl is currently broken, so there is no binary:

I remember fixing this a while ago - it wasn't as simple as casting,  
because the structures are wrong, but I'll see if I can dig out the fix.

My guess is that you forgot to re-install them (or you have old local  
packages somewhere). This happens most often if you install libraries  
in your home directory. On OS X it's usually much safer to use system- 
wide packages, because that prevents cross-version problems, version- 
confusion and the GUI allows you to re-install them automatically.  
That doesn't work for your local packages in home.

Cheers,

*) - for completeness, you also get this error if you install a  
binary that was not built for the universal R or if the ppc  
architecture build failed. However, neither should not happen with  
CRAN binaries.
