deprecated functions - Gtk2::AboutDialog

["Gabor Szabo" <szabgab gmail com>]

I have an Gtk2::AboutDialog in the application (using glade). I am
trying to set its name
using $about->set_name() which works on Ubuntu. When I try the same on
Camelbox I get a warning about
set_name being deprecated and that I should use set_program_name() instead.

So I guess it is just that there are different versions of Gtk2 on
these platforms.

But what should I do in such cases?
What is the recommended way to deal with this?
