But it looks like you have not installed XQuartz.  If you have done so 
in the past, reinstall it.  As you are on Intel Mac, I think you want 
XQuartz 2.7.11 as I believe that is what is on the build machine.

As a general BTW, I had to guess that you installed a binary package and 
the output below is from library(rgl).  But please do tell us such things.
