Your student (and the other students who are experiencing problems) can verify this by trying to load the tcltk package directly, via library(tcltk), to see whether he gets the same error.

I suggested that the user install the current version of X-Quartz, but you student apparently already has done that. Is it possible that there's an old version of X-Windows on the student's computer?
>> I assume that your students have been following the Rcmdr installation instructions for Mac OS X at <http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html>. Have any of them been successful? Are all the problems identical? You mentioned that another student installed a version of Tcl/Tk independently of R. I suppose that this could cause problems if the wrong Tcl/Tk is invoked.

Those are the sources - not very useful to end-users ;).
R 3.0.1 comes with the necessary binary so there is no need to download anything else.

Note that we don't use XQuartz - the default is to use system X11 (hence the /usr/X11 path). If XQuartz replaces the system X11 (by symlinking into /usr/X11) then it is used, but that is only the default on OS X versions that don't come with X11 at all.

^^-- this is irrelevant - TclTk uses /usr/X11:
$ otool -L /usr/X11/lib/libfreetype.6.dylib
/usr/X11/lib/libfreetype.6.dylib (compatibility version 14.0.0, current version 14.2.0)

>> I too am teaching with the Rcmdr this Fall, and about half the students in my (small) class have Macs. None have experienced problems with the tcltk package or version 2.0-1 of the Rcmdr under R 3.0.1. Nor have I on my Mac, running OS X 10.8.5 and XQuartz 2.7.4
