Thanks, that's what I wanted to confirm. I know rosbuild is deprecated, but the status of that deprecation is not visible in much of the documentation, and there are many inconsistent and erroneous pieces of documentation scattered around the ros.org site. I think it's important to try to keep documentation accurate, which is why I pointed out what I thought was an error. The wiki should recommend catkinization, and it should explain that this is because of the deprecation of rosbuild.

Thanks for the clarification.

2013-09-20 18:43:16 -0500 asked a question Why does the wiki claim that ROS packages using gazebo must be catkin packages?

The wiki claims that ROS packages depending on gazebo have to be catkin (wet) packages, and not rosbuild (dry) packages.

http://gazebosim.org/wiki/Tutorials/1.9/Overview_of_new_ROS_integration#Catkin

But if you're using the "standalone" gazebo APIs you can just access whatever you need using cmake either way. If you're using APIs from any of the ROS catkin (wet) packages in the gazebo_ros_packages metapackage you can still depend on those packages from a rosbuild (dry) package (dry can depend on wet, it's wet that can't depend on dry).

Is this an error, or am I missing something?

2013-09-20 18:22:46 -0500 asked a question Why is the gazebo ubuntu package available both at packages.osrfoundation.org and packages.ros.org?

The current installation instructions for gazebo state that one should only use the information on gazebosim.org, which points to the repository at "http://packages.osrfoundation.org/gazebo/ubuntu". However, the standalone version of gazebo also seems to be available at "http://packages.ros.org/ros/ubuntu" (at least for precise).

Given all the recent changes regarding the gazebo website, installation instructions, ROS integration, etc. (and the inevitably resulting confusion), wouldn't it be better to just have gazebo in the osrfoundation.org repository?

This would avoid confusion due to different versions being available in the different repositories, and it would also make it clear that gazebo is really a standalone project, which can be integrated with ROS with help from packages from the gazebo_ros_pkgs ROS meta-package.
