[ros-users] Request for Clue: OSX-specific linker flags, dependency resolution

Jack, that patch looks exactly right. However, I am getting strange
behavior.

When I *haven't* applied the patch, this is my output:

dyn137-110-111-179:camera1394 rubinet$ rosdep install camera1394
Failed to find rosdep glut for package camera1394 on OS:macports
version:macports
Failed to find rosdep libdc1394-dev for package camera1394 on OS:macports
version:macports
ERROR: ABORTING: Rosdeps [u'glut', u'libdc1394-dev'] could not be resolved

When I *have* applied the patch, this is my output:

dyn137-110-111-179:camera1394 rubinet$ rosdep install camera1394
Failed to find rosdep glut for package camera1394 on OS:macports
version:macports
ERROR: ABORTING: Rosdeps [u'glut'] could not be resolved

I tried to fix this by adding an empty macports entry (macports: |) to
everywhere that rosdep.yaml has "glut". From my investigation, this only
seems to happen in the geometry package. Yet the problem persists.

Another strange thing is that I get the same behavior *regardless of whether
libdc1394 is installed* (It is easy to uninstall and reinstall).
