[Rd] Installation of RGtk2 (PR#10519)

[Duncan Murdoch]

This isn't an R bug.  You should send contributed package problems to 
the package maintainer, in this case Michael Lawrence.

You need to install GTK; it's not included as part of the package.  See 
this page for instructions:

http://www.ggobi.org/rgtk2/

It would probably be a good idea for the R package to recognize this 
omission and print more helpful error messages, but setting that up is 
tricky.  Michael, if you want help, please contact me offline.
