I use Fedora 11 (soon 13) with Tcl 8.5 (don't forget all the -devel RPMS 
on Red Hat-like systems):

tcl-8.5.6-6.fc11.i586
tcl-devel-8.5.6-6.fc11.i586
tk-8.5.6-4.fc11.i586
tk-devel-8.5.6-4.fc11.i586
itcl-3.4-4.fc11.i586
itcl-devel-3.4-4.fc11.i586
itk-3.4-4.fc11.i586
itk-devel-3.4-4.fc11.i586
iwidgets-4.0.2-2.fc11.noarch

Are you using x86_64? I believe I am sitting on a patch to fix some bad 
assumptions with that... Still need to test them some more, though.

Yeah, definitely cannot do that...

You can use:

  --with-tcl              directory containing tcl configuration 
(tclConfig.sh)
  --with-tk               directory containing tk configuration 
(tkConfig.sh)

Normally, you only need to use --with-tcl -- the configury will assume 
that tkConfig.sh is in the same place. I believe I tested all this when 
I did this work a while ago, but I might have missed something. Testing 
three different configury scenarios can get a little confusing.

Do "make configure-gdb" just after you do the configure. This is how I 
normally do it (when I do configure-gdb instead of all-gdb):

$ CFLAGS="-g" ../src/configure --prefix=/home/keiths/insight/HEAD/built
[snip]
$ make configure-gdb
[now you can check the configure log in gdb/]
$ make all-gdb

What version of insight are you trying to build, BTW. It might make a 
difference. [It might not, either. I remember fixing some build bugs a 
while ago...]

I've built Insight this way for almost two-three years now, and I've 
used the resulting executable for my daily work on archer, so it can be 
done.
