Maybe you can run

$ rosdep check rviz_qt
and
$ rosdep check rosgui_rviz

to check where this error is coming from.

I just filed a bug about a problem in the rviz_qt rosdep.yaml, but this 
should not affect you, if you are on OSX.
https://code.ros.org/trac/ros-pkg/ticket/5312
After I fixed that locally, I got not errors when running
$ rosmake --rosdep-install rosgui_rviz

Cheers,
Dorian
