Hi

I am trying to set an arduino node. Here is the short version of the story.

I defined a custom message ("lowlevel/Arduino") and generated the
appropriate header using the script for that. The arduino code
compiles alright. However, I am having a problem on the python_node
side: it cannot load my package 'lowlevel':

[ERROR] [WallTime: 1314328569.317936] Cannot import package : lowlevel
[ERROR] [WallTime: 1314328569.318390] Failed to parse subscriber.

However, if I run the following commands in ipython, it seems to work:

In [1]: import roslib; roslib.load_manifest("rosserial_python")
In [2]: import rospy
In [3]: roslib.load_manifest('lowlevel')
In [4]: m=__import__('lowlevel.msg')
In [5]: m.msg.Arduino
Out[5]: <class 'lowlevel.msg._Arduino.Arduino'>

What am I doing wrong?
