Hello!

I have a problem in installing wxWidgets in Ubuntu 12.10. When I try to install it by following the instructions given in the wiki page of wxWidgets, I get an error message that says something like the path og GTK is not identified. Not sure about that; so below is the message that I get when I try to configure it.

Code:
