Got it!  Here's what I had to do.

1) Download tcl8.4.12-src.tar.gz and tk8.4.12-src.tar.gz
http://www.tcl.tk/software/tcltk/downloadnow84.html
2) Unzip and untar them into /opt/TclTk.
3) ruby extconf.rb \
    --with-tcl-include=/opt/TclTk/tcl8.4.12/generic \
    --with-tk-include=/opt/TclTk/tk8.4.12/generic
4) make
5) make install
