That is not what I am reading. libfreetype.6 version 13 is the reported problem with a need to update to version 14. > I'm not sure why that happened, and there was a previous message about a > similar problem on the list.

I'm not really a student but maybe this will be useful anyway. There is a version of Tk at: http://r.research.att.com/src/tk8.6.0-src.tar.gz ... which appears to be the most up-to-date version.
