[R-SIG-Mac] Segfault Error in GUI version of R

[Prof Brian Ripley]

The version of R.app you are using (built for OS X 10.6 before 10.9 was 
released) is not compatible with Mavericks (10.9): are you using that?

If so, please update your R to 3.0.2, or if you do not want to do that, 
update just R.app from r.research.att.com (which just now was serving me 
an empty page).

BTW, the 'bug' seems to be in OS X system calls in 10.9: we have merely 
worked around it.
