One thought is that if this is to use gsubfn or sqldf (which uses
gsubfn) then you can get them to not use the tcltk code but use R code
instead by either of these two means:
1. issue the command:
options(gsubfn.engine = "R")
before issuing your library(sqldf) or library(gsubfn) command. You
can put the options command in your .Rprofile if you like and then you
will have it on every session.
or
2. use a build of R that has no tcltk in it. In that case it will
recognize it and switch to using R. I believe one such build exists
for the Mac.
