Tcl/Tk is part of the standard R 3.1.2 installation. You should not have had
to do a separate install (though perhaps you didn't). You shouldn't need
XTools (though if it's installed, I suppose that it should provide otool).

When the tcltk package loads it checks for the presence of otool, which I
believe is intended to determine whether there's a functioning X Windows
(though why this check is used is unclear to me).  This is a relatively new
check and may be source of the problem, or something may be broken in your
system. You might try reinstalling XQuartz and perhaps uninstalling the
Tcl/Tk that you installed separately from R (if you did so).

This isn't necessary: the  tcltk package is part of the standard R
installation.

There's some problem with the CRAN mirror that you're accessing, but tcltk2
should have been installed along with the Rcmdr package and needn't be
installed in a separate step.

I'm copying this response to the R-SIG-MAC email list and to Simon Urbanek
and Brian Ripley, who are likely to have more insight into your problem that
I do.

Best,
 John
