Why does rqt_image_view still depend on the workspace that was used for building it although it was installed to /opt/ros/indigo? Is that desirable? What can I do to fix this?

 rosrun rqt_image_view rqt_image_view

I don't think this actually depends on those files. Maybe it is just the source path baked into compiled python paths. Try removing / renaming that build dir. Fr me this results in the same error.

Now it seems we need to update the homebrew formula for pyqt to the 11.1 release, but it gives me a linker error...

EDIT: See hombrew issue https://github.com/Homebrew/homebrew/...

EDIT 2: I confirmed that the path referring to build is indeed baked into the installed compile python files, which kind of makes sense. So this is not a dependency to the build folder and the error is something else, namely outdated pyqt. Unfortunately there seems to be a linking issue for the recent pyqt version on OS X / clang, see the above github issue.

Update: It seems we have been able to fix the PyQT formula. With the current version in that pull request I can run rqt successfully. The formula will hopefully get merged into homebrew soon.

Update2: PyQt 4.11.1 has been released into homebrew. After brew update and subsequent brew upgrade pyqt, you should be able to run the GUI. Maybe you need to also brew reinstall pyqwt after upgrading pyqt.

When renaming it back to ros_catkin_ws it still results in the same error. No wonder, there is nothing inside ~/ros_catkin_ws/build_isolated/python_qt_binding/bdist.macosx-10.9-intel

I don't think the error is related to the contents of that directory. The python code is being executed evem though the files are not in that directory, as you can see from the stacktrace. I think this is purely an issue of PyQt being outdated and the wrong stack trace ...
