For those interested in being able to use py-imagingtk on 1.6, the
following may help.

The patch below results in a python binary that is linked against
libpthread.so as _well_ as libpth.so.  This is ugly to be sure, and
probably the reason for the --with-pth in the first place, (even
--without-pth doesn't stop it linking with libpth.so)

Anyway, linking against libpthread.so avoids the unresolved symbols
that otherwise result when _tkinter causes libtcl to be pulled in
which requires libpthread.

I'm not planning to commit this since I expect there's a better fix out
there (upgrading to 2.0 is a simple one ;-), but it may help others in
the meantime.
