The tcl/tk extensions blt and iwidgets seem to conflict in Fedora 9 beta:

Error Summary
-------------

Same results when installing iwidgets first and attempting to install blt later.

Additional info:
On Fedora 7, blt didn't contain any man pages, maybe that explains why the
problem didn't occur there. I have no fedora 8 system available to compare the
results there.
