DUDE!! Did you happen to look at the number of posts that acid-kewpie has???
Don't just tell him he's wrong!
You most certainly ARE missing gtk. Now, you may have installed it, and for reasons yet undetermined your system isn't seeing it (haven't run ldconfig); or it may be something else. We won't know until we have further info from you. But, I will guarantee you, with responses like that, NO ONE is going to respond to this thread!!
