[R] tcltk on Windows 98

[Setzer.Woodrow@epamail.epa.gov]

I've written an application that uses the tcltk package, and have
distributed it to a few people to use here in the Agency on Windows 98
machines.  It has worked just fine on all but one of those machines.  On
that one (system information quoted below), we persist in getting the error
message:

> require (tcltk)
Loading required package: tcltk
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library
"C:/PROGRA~1/R/RW1021/library/tcltk/libs/TclTk.dll":
  LoadLibrary failure:  One of the library files needed to run this
application cannot be found.
[1] FALSE

TCL_LIBRARY is set (when it is not, the error message is different), and we
have reinstalled Windows 98, tcltk, and R at least once.  The above path
points to tcltk.dll (yes, there is a difference in capitalization, but I
don't think that is supposed to matter on Windows -- it doesn't on my
system, anyway).

Has anyone else seen this problem, and have a fix?  Is there a way to get a
list of library files required by a dll?

Thanks for your patience!
