[R-SIG-Mac] 64 bit Mac GUI

[Prof Brian Ripley]

You should be able to install all the packages you need on a 64-but 
machine -- the Linux community has been doing so for years, and 64-bit 
Linux has been part of the testing equally for several years.  (I only 
have 64-bit Linux systems.)

With 'statnet', the chain of dependencies includes 'rgl' where you 
only have access to the X11 version (and will need to modify the 
sources to build it).  I suspect that this is actually a problem with 
the statnet suite - 'shapes' claims to depend on rgl but probably 
should only suggest it.  This is the not the place, but the authors of 
the suite need to be asked to study and follow 'Writing R Extensions'.

We know about the rgl issues, and workarounds are being discussed.

'igraph' compiles from the sources on x86_64 Mac OS -- what problems 
did you encounter when you tried?

Running 32- and 64-bit R on the same machine is very simple (start up 
with R --arch=), but I suspect what you are talking about is running 
R.app (the GUI).  I'll leave Simon to explain that.
