Hi,

I tried to install ROS/Hydro in OS X10.9 with homebrew following with ：http://wiki.ros.org/hydro/Installation/OSX/Homebrew/Source

When I run $ rosdep install --from-paths src --ignore-src --rosdistro hydro -y, I got

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:

qt_dotgraph: No definition of [python-pygraphviz] for OS [osx]

qt-4.8.6 and graphviz-2.38.0 are already installed.

I am experiencing the same error. I am installing on OS X Yosemite following the directions at "http://wiki.ros.org/indigo/Installation/OSX/Homebrew/Source"

I still can not solve this problem. How about you?

Finally, I fixed it by

$ rosdep install -s --from-paths src --ignore-src --rosdistro hydro -y --skip-keys "python-pygraphviz"

referenced from here

I don't know whether there will be further problems by doing this. But it works now.

I was having this same issue and fixed it with the following:

I was also running Macports (Homebrew does not like this), so the first step was to move /opt/local to ~/macports "sudo mv /opt/local ~/macports" per the "$ brew doctor" recommendation when it discovered macports config files. My guess is that this is what ultimately fixed the issue, but I also took further steps suggested in the post linked below.
Manually forced generation of dot config file: $ dot -c
Verified the the existence of the folder "/usr/local/lib/graphviz" and the config6 file.
