Recently I tried the new prerelease test system, following http://wiki.ros.org/bloom/Tutorials/PrereleaseTest

But when running the prerelease.sh script, I get this error in build STEP 4 ( missing dependency ? python 2 / 3 conflict ? ) :

# BEGIN SECTION: Generate Dockerfile - devel tasks
+ export TZ=KST-00
+ export PYTHONPATH=/tmp/prerelease_job/ros_buildfarm:/opt/ros/indigo/lib/python2.7/dist-packages

  File "/tmp/prerelease_job/ros_buildfarm/ros_buildfarm/templates/__init__.py", line 3, in <module>
    from em import Interpreter
ImportError: No module named 'em'

any idea where it comes from / where I can fix it ?

also :
$ sudo pip install em
Requirement already satisfied (use --upgrade to upgrade): em in /usr/local/lib/python2.7/dist-packages
Cleaning up...

I ll be happy to help testing this new prerelease test system, since I am trying to release a new package it makes complete sense :-) So please let me know if there are things I should try out.

Cheers,
