GTK+ library errors while compiling GNOME programs

["\"Freddy Ng\" <\"Freddy Ng\""<j c ng ic ac uk>]

I get various error messages when compiling some
GNOME programs like Balsa, gnomeicu, etc. Most are
about the gtk-config file ( which I have but
nothing is inside) or about my libraries not being
up to date. I downloaded and installed the latest
GNOME version which puts the GTK+ version at 1.2.
Anyone knows how do I resolve this problem?
Thanks!
