I should have said that rattle does not declare a *strict* dependency on 
RGtk2.  When I try to run rattle() I see

 > rattle()
Error in rattle() :
The RGtk2 package is not available but is required.
Please install the package using, for example:

   install.packages("RGtk2")

which would have failed.

Maybe you have some non-CRAN version of RGtk2 installed?

rattle's DESCRIPTION does say

   Note that RGtk2 and cairoDevice have been archived on CRAN.
   See <https://rattle.togaware.com> for installation instructions.

If you followed that, it would be something to take up with the 'rattle' 
maintainer.

Loading rattle seems to have worked -- it was running rattle() that failed.
