Hello,

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

Note : I am using indigo, and I followed
http://wiki.ros.org/regression_tests#How_do_I_setup_my_system_to_run_a_prerelease.3F
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

    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,
