Problem running insight on Fedora 9

Neither insight-6.6 nor insight-6.8 run on Fedora 9 with latest updates:

This probably means that tk wasn't installed properly.

I found this: http://aspn.activestate.com/ASPN/Mail/Message/tcl-core/3668443

"Your system has a very recent release of X11 from X.org.  That release
broke interface compatibility, so you also must get the very latest
release of Tk, 8.5.4, that's been modified to account for that."


If that's the case with insight too: are there any plans to update Tcl/Tk?

Thanks
