<div><br></div><div>Nicolás, you can follow instructions on our wiki page to install ua-ros-pkg repo here: <a href="http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall" target="_blank">http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall</a>. It assumes you are doing a fresh svn based install. Let me know if you run into any trouble.</div>

<br>
There are multiple ways to locate this package:<br>
<br>
$ roslocate svn erratic_gazebo<br>
<a href="https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/wg_robots_gazebo/erratic_gazebo" target="_blank">https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/wg_robots_gazebo/erratic_gazebo</a><br>
<br>
On the wiki page, look for "Source: svn"<br>
<a href="http://www.ros.org/wiki/erratic_gazebo" target="_blank">http://www.ros.org/wiki/erratic_gazebo</a><br>
<br>
However, I'll note that the erratic packages will soon be taken over<br>
by those provided by ua-ros-pkg, as they are better maintained. I<br>
believe their equivalent package is:<br>
<a href="http://www.ros.org/wiki/erratic_gazebo_plugins" target="_blank">http://www.ros.org/wiki/erratic_gazebo_plugins</a><br>
<br>
I've also patched roslaunch (r11979) to not have as bad of an error<br>
message when this occurs.<br>
<br>
cheers,<br>
Ken<br>
