[R] problem with RGtk

[Anna Oganyan]

Dear List,
I would like to ask about package RGtk2 with which I have a problem.
I will very much appreciate if somebody could tell me what I need to do.
I need to install a  package scdMicro and it depends on gWidgetsRGtk2.
I am working on MAC, version 10.5.8.
When I try to load gWidgetsRGtk2 (or RGtk2), it asks me:
"Instal GTK+?"

I installed Gtk+ from CRAN, and added a path:

export PATH=$PATH:/Library/Frameworks/GTK+.framework/Resources/bin

But next time I try to load gWidgetsRGtk2 (or RGtk2), I get the same message: "Instal GTK+?"  

Below I included the error message I got.
