Sometimes I've seen this under MS/Windows and the solution has been to
reinstall the gtk libraries independent of R and to make sure this is the
one installed:
http://downloads.sourceforge.net/gladewin32/gtk-2.12.9-win32-2.exe. It looks
like glade was not in the gtk libraries you installed?  Hope that helps.

Graham
