   Do you want to link against Gtk2 or Gtk1.2 ? If you want Gtk2, you should
use pkg-config --cflags --libs gtk+-2.0 on your configure.in to resolve the
libs and flags to the compiler. If your Gtk2.0 installation is on the standard
directory, it should resolve fine, else, you will need to export
PKG_CONFIG_PATH to point the the directory where the .pc files are - I can send
more info on that if you need (For now I am assuming that you have on standard
dir).

    Make sure you actually have GTk2.0 installed.

Good Luck.
Harring.
