OS X install errors

[migel]

I'm tried to follow the instruction for installing with a rosinstall file:

mkdir ws && cd ws
wstool init src https://raw.github.com/wg-perception/object_recognition_core/master/doc/source/ork.rosinstall
cd src && wstool update -j8
cd .. && rosdep install --from-paths src -i -y
catkin_make
source devel/setup.bash

Got the following errors:

mk@mk-mbp:~/ros_ws2/src$ cd .. && rosdep install --from-paths src -i -y
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
object_recognition_reconstruction: No definition of [meshlab] for OS [osx]
object_recognition_core: No definition of [couchdb] for OS [osx]
ecto: No definition of [python-pyside] for OS [osx]
object_recognition_renderer: No definition of [sdl] for OS [osx]

Those dependencies need to be added to https://github.com/ros/rosdistro/blob/master/rosdep/osx-homebrew.yaml
@wjwwood, I'd appreciate if you could add those. Thx

What's the difference in sdl and sdl_image? https://github.com/ros/rosdistro/blob/master/rosdep/osx-homebrew.yaml#L640

Also it would be great if the people who need the keys and are using them could contribute them, maybe @migel can take a crack at it? http://docs.ros.org/independent/api/rosdep/html/contributing_rules.html

@migel, please follow the instructions at http://docs.ros.org/independent/api/rosdep/html/contributing_rules.html and add the dependency keys you need: those are fairly standard so it should be easy for you.

@wjwwood , sdl_image is the image part of SDL :p

Ah, I didn't know if that was a duplicate key or not. It seems strange that there is an OS X key for sdl_image, but not for sdl.
