I had a problem on debian with both tcl8.3 and tcl8.4 installed - only
the headers for tcl8.3 were included (because of some annoying obsession
to decompose debian package in 'runtime' and 'devel') but the ruby
config was detecting the 8.4 libraries and trying to include files from
/usr/include/tcl8.4.
Well I guess you could modify the ruby setup script (in
ext/tcltklib/extconf.rb or something like that, I guess this would be
the nicest thing to do to debug it) or the makefile generated in
ext/tcltklib/Makefile, what I did is deinstall the 8.4 library, compile
ruby, then reinstall it (actually I first tried installing the 8.4
headers, but then ruby-tk would hang). IF you are having the same
problem I had, of course.
