Not sure what is going on, but your reference to gtk is sign that
something is wrong. The j801 release has nothing to do with gtk and is
all about Qt, jconsole, JHS.
My guess is that you've got the wrong download. Go back to the web
site and proceed slowly (refresh every step of the way to avoid cache
troubles) and be sure you've got the latest stable j801 release.
