rosserial_arduino failed to generate libraries for packages

edit

I am following the tutorials for rosserial_arduino and when I run

rosrun rosserial_arduino make_libraries.py

I get the error:

*** Warning, failed to generate libraries for the following packages: ***
map_msgs
relative_nav_msgs

I don't care about the map_msgs, but the relative_nav_msgs are custom message types that I need.

It looks like it breaks part way through the messages, this is the exact formatted output

Exporting relative_nav_msgs
Messages:
  Path,FilterState,Waypoint,Snapshot,Goal,DesiredVector,NodeInfo,Keyframe,Voltage,DEBUG_Controller,PartialState,Exporting turtle_actionlib

So it looks like something bad happened after the PartialState message and it skipped to Exporting the turtle_action lib.

Also, is there a way to turn off which types are built? For example, I don't actually care about the map_msgs, can I omit them from ros_lib?
