[R] "Tcl/Tk support is not available on this system, " RH 9, R 1.7.0-1

[Jonathan Baron]

In trying to run John Fox's new Rcmdr package on Redhat Linux 9,
I got this error message.  The problem is in loading the tclck
library.  library(tcltk) produces the same error.  It has been
discussed before, e.g.,
http://finzi.psych.upenn.edu/R/Rhelp02/archive/11898.html but
with respect to earlier versions of Linux and R.
I tried updating to the latest RPMs of tcl and tk (8.3.5-89), but
that didn't help.  Otherwise I just have the standard RH9
installation.  Has anyone gotten tcltk to work on RH9?
