Do you know where libfreetype.6 comes from? Is it installed independently of Tcl/Tk and XQuartz? If so, do you know how to update it?

Version 8.6-0 of Tcl/Tk for X-Windows is included in the R 3.0.1 installer for Mac OS X. Is it possible that it doesn't get installed if there's already a Tcl/Tk for X-Windows installed?

So tcltk and the Rcmdr 2.0-0 work on your system because you have a sufficiently up-to-date libfreetype.6. It would be additionally helpful to be able to answer the following questions:
(1) Why is it that some users have old versions of libfreetype.6.
(2) Why doesn't installing the newest versions of R (which includes Tcl/Tk) and XQuartz, not solve this problem?
(3) What can users experiencing this problem do to fix it?
If I knew the answers to these questions, I could update the Rcmdr installation notes to help users avoid the problem.
Thank you for your help,
