William,

Homebrew + ROS: followed your instructions on the wiki (https://github.com/wjwwood/ros-osx/tree/master/electric-lion-homebrew) and there were a couple of warnings about version number (when running python apply-patches.py ./patches $ROS_WORKSPACE), shown below. Note, I cut everything out that wasn't a warning.

[kevin@TARDIS electric-lion-homebrew]$ python apply-patches.py ./patches $ROS_WORKSPACE
INFO   : Using patches path: /Users/kevin/tmp/ros-osx/electric-lion-homebrew/patches

Then running rosmake --rosdep-install ros ros_comm common_msgs fails and gives me:

if I remove the --rosdep-install from the command it say:

I can go to that web address and see the file, so I don't understand why ROS can't. Any thoughts? Oh and I moved macports to _opt so it shouldn't be an issue.
Thanks.
