tcltk and Windo$e

I am running R1.6.2 under windo$e98. I have followed the instructions in the
Win port faq concerning tck, but when I try 'library(tcltk)', I get

Error in dyn.load(x, as.logical(local), as.logical(now)) : 
       unable to load shared library
"C:/PROGRA~1/R/RW1062/library/tcltk/libs/tcltk.dll":
 LoadLibrary failure:  One of the library files needed to run this
application cannot be found.
Error in library(tcltk) : .First.lib failed

Assuming that tcltk.dll really is there, this probably means that it
can't find one of the dlls that it uses.  I'd guess one of the
environment variables isn't set properly, and I think it's the PATH
that's used to find the DLL.  Use Sys.getenv("PATH") and
Sys.getenv("TCL_LIBRARY") inside R to make sure they look right.

Even better: I recommend upgrading to 1.7.0:  in the new release the
TCL/TK files are automatically installed properly.
