I'm afraid the procedure is not trivial, if no precompiled packages are
available for the particular system; they would have to compile tcl and tk
with --enable-threads (iirc that's the name of the ./configure option) and
then compile python against the new Tcl/Tk.

However, when I take a second glance at the traceback, in particular the
following lines:

  File "/awars2a/Applicatio​ns/viewvc/viewvc-1-1​-18/bin/standalone.p​y",
    line 671, in ready self.title_lbl.confi​g(text='ViewVC standalone
    server at\n' + server.url)

I am beginning to suspect (though I admit that I was too lazy to
thoroughly look through the code) that in fact the code is buggy as it
seems to try to change the Tkinter.Label's text from the child thread.
Even better, when I look at:
http://viewvc.tigris.org/svn/viewvc/trunk/bin/standalone.py
these lines (resp. the use of Tkinter at all) are missing, so maybe they
actually found out about the bug and fixed it.

So I guess that maybe it is the best bet to try the latest
development version of viewVC.

Regards

Michael
