This is a heads up on a change to the ogre rosdep rule.
Right now the `libogre-dev` resolves to `libogre-1.9-dev` on Trusty, which is what rviz on Trusty uses and therefore depends on.
Currently the version of Gazebo in Trusty instead depends on `libogre-1.8-dev` which conflicts with `libogre-1.9-dev`. Gazebo has some open issues related to `libogre-1.9-dev` and therefore we are proposing to change the `libogre-dev` rosdep rule to be `libogre-1.8-dev` for Trusty, which will change rviz's dependency to also be `libogre-1.8-dev`.
If you have a problem with this or are also using the `libogre-dev` rosdep key then please reply here or on this issue:
All of our testing indicates that rviz works fine with ogre 1.8 (that is the version used in Saucy).
Thanks,
