I did. I've insured that tcl and tk (with development files) are 
installed. I verified that the library files are in /usr/lib, and the 
include files are in /usr/include/tcl8.4

I then rebuilt ruby with the following commands:
   make clean
   ./configure --prefix=/usr/ --with-tcllib=tcl8.4 --with-tklib=tk8.4
        --with-tcl-include =/usr/include/tcl8.4 --with-tcl-lib=/usr/lib
        --with-tk-include=/usr/include/tcl8.4 --with-tk-lib=/usr/lib
   make
   sudo make install

Still, require 'tk' fails telling me that tcltklib isn't there.

I've grepped the configure script and the makefiles for 'tcl' and 'tk' 
and don't see where the configuration parameters are even used. grep tk 
doesn't find anything, and grep tcl doesn't find anything practical.

Beyond that, I don't see anything to help me diagnose why tcltklib isn't 
being made.

Any clues, or is it just not possible to configure?
