rgl, Leopard, 64 bit

Looking through the archives, I see that the developers of rgl don't have 
access to a 64 bit Mac, and are waiting for someone else to take the 
initiative and make an appropriate patch.  Unfortunately, I think this is 
beyond my abilities.  Has anyone been able to get it to work?

I now have a 64-bit Mac (10.5.6), and probably the abilities. If you 
could collect together the relevant posts, I will endeavour to take a 
look (unless Simon has already got there).  Please post a follow-up 
posting for future reference, and include the rgl maintainers (who I 
suspect do not read R-sig-mac).

Thanks,
Matt
