[Dev-C++] GTK, update gtk manually?

[<eas...@t-...>]

Hi , 
Everybody I am using Dev C++ and its GTK-Package (2.0.3).
But now I have a little problem , which was solved in the latest stable
version of GTK (2.0.9) and Pango 1.0.5.
So I would like to ask you how to upgrade my gtk manually, or is there a
newer version of GTK-Package???

Thanks for all,
Martin
