[R-SIG-Mac] Problems loading Rcmdr on a Mac 10.7.2 and a Mac 10.6.8

[Simon Urbanek]

Sarah,

note that 10.7.2 is way old - there have been many patch releases since then so first thing I'd suggest is to run Software Update. XQuartz doesn't remove system X11 if installed, so it's not necessarily relevant (it depends on the local setup) - OS updates may be more important here. But if in doubt, re-install XQuartz. R binaries assume a system that is up to date, regardless of the major OS X version.

As for the other student - do not install anything extra - R 3.0.1 already comes with everything that is needed. The additional downloads were needed for older versions of R.

Cheers,
Simon
