[R-SIG-Mac] RGtk2 problems

[Anna Oganyan]

Dear all,
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. I have the latest R version (2.10.1).
When I try to load gWidgetsRGtk2 (or RGtk2), it asks me:
"Instal GTK+?"

I installed RGtk2 (version 2.14.3 from  http://r.research.att.com/gtk2-runtime.dmg
), 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+?"  
And of course all packages dependent from RGtk2 are not loading.

I also tried to install GTK 2.18.5-X11.pkg (from http://r.research.att.com/libs/GTK_2.18.5-X11.pkg ) - but in this 
case when I try to load RGtk2 - R hangs.

Below I included the error message I get when RGtk version 2.14.3 is installed.
