catkinize throws ValueError: Path is not a rosbuild stack

edit

Hello and happy new year!

I am trying to migrate some simple ROS packages (Fuerte) to Hydro and catkin.

As far as I understand the catkinize programm should be able to migrate packages from rosbuild to catkinize. But so far it has failed with two simple packages showing this traceback. According to http://wiki.ros.org/catkin/migrating_from_rosbuild no special preperations, except for setting up the workspace should be required.

 catkinize sas_utils 1.0.0

    Traceback (most recent call last):
  File "/usr/local/bin/catkinize", line 5, in <module>
    pkg_resources.run_script('catkinize==0.1', 'catkinize')
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 499, in run_script

    path)
ValueError: Path is not a rosbuild stack, missing stack.xml at sas_utils

Why does it require a Sack as an input?

Furtermore I would like to know what the version number (the second input Parameter) is good for and when it becomes relevant.

Thats my OS specs:

• Linux Grot-M58p 3.8.0-34-generic #49~precise1-Ubuntu SMP Wed Nov 13 18:05:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
