[R-SIG-Mac] R 32-bit suddenly the default on Mountain Lion 10.8.2?

[Prof Brian Ripley]

Marc,

Start with 'which R', or run /usr/bin/R explicitly.  That should be a 
symlink to

/Library/Frameworks/R.framework/Resources/bin/R

and that should be a symlink,  If it is not like

lrwxr-xr-x  1 root  admin  3 28 Oct 08:03 
/Library/Frameworks/R.framework/Resources/bin/R@ -> R64

or is linked to R32, change it to point to R64.

It is the installer which determines what it links to.  Specifically 
https://svn.r-project.org/R-dev-web/trunk/CRAN/QA/Simon/R-build/packaging/leopard/scripts/postflight 
.

If running /Library/Frameworks/R.framework/Resources/bin/R64 is not 
x86_64, come back to us.
