Failing human resource demo

[Martin Schneider]

Hi everyone,

I started to look into Drake. I'm currently trying to run the human Resource demo. But I failes with the following stacktrace:

martin@note-9028:~/workspace/drake/humanResource$ drake
The following steps will be run, in order:

  2: /home/martin/workspace/drake/humanResource/././for_HR.csv <- /home/martin/workspace/drake/humanResource/././people.json [missing output]

If I try the "simplest" workflow explained in the Tutorial, all works fine.

I hope someone can spot my error and can help me.

Do you have Ruby installed? It seems to be looking for Ruby and not finding it.
