If you have Ruby (1.8), Tcl and Tk all together on the same Linux
system, they must all be compiled with the same setting for "pthreads"
-- either all of them have it set or all of them don't. Ruby will
complain during either configure or make, I forget which, if you tell it
to do the opposite of what it has determined you did for Tcl and Tk.
