A recent commit started making use of some new functionality of rxplot that will be released in Electric. For now to be compatible you need to:
- checkout rxtools from SVN (diamondback tag)
- put this rxtools in your ROS_PACKAGE_PATH
- apply the patch from https://code.ros.org/trac/ros/ticket/3527
Note that in unstable/Electric the implementation is slightly different. At some point I'll harmonize things so the launch files will work with either a patched diamondback rxtools or with unstable/Electric. Until then this ticket is here in case someone runs into this.
