A few months ago, I had successfully installed ROS Indigo on Mac OS X using Mike Purvis' install script ( https://github.com/mikepurvis/ros-ins... )

Today, I decided to update my installation and also install the navigation stack. First, I did:

rosinstall_generator navigation --rosdistro indigo --deps --tar | wstool merge -t src -
wstool update -t src -j8

And that seemed to work just fine. But then, when I tried to get the dependencies with:

rosdep install --from-paths src --ignore-src --rosdistro indigo -y --as-root pip:no --skip-keys="procps" --skip-keys="gazebo"

I get the following error message:

ERROR: Rosdep experienced an error: Multiple packages found with the same name "tf2":

Please go to the rosdep page [1] and file a bug report with the stack trace below.

rosdep version: 0.11.4

I ignored it and marched on with the installation. But invoking catkin build resulted in a similar error:

The geometry_experimental repository was renamed to the geometry2 repository. When you reran the rosinstall_generator it create the new repo, but rosinstall does not remove unknown packages from your workspace. If you have no local changes you can just remove the geometry_experimental repository and make sure it's not in a .rosinstall file. If you have local changes you can remove the new geometry2 repo and rename the geometry_experimental to geometry2 and remove any references to geometry_experimental

Perfect, thanks Tully! I generated a fresh .rosinstall and successfully built everything, including the nav stack.
