new_version.py looks for ./bin/buildout !?

Hi,

When lauching:

$ ./bin/bob_new_version.py --q

within the bob.example.project package, I get the following error message:

  Assuming stable version to be 0.0.1 (since current version 0.0.1a0)  
  Assuming latest version to be 0.0.2a0 (since current version 0.0.1a0)
  Traceback (most recent call last):
    File "./bin/bob_new_version.py", line 23, in <module>
      sys.exit(bob.extension.scripts.new_version())
    File "/idiap/group/torch5spro/conda/envs/bob-2.6.2-py27_0/lib/python2.7/site-packages/bob/extension/scripts/new_version.py", line 197, in main raise IOError("The bin/buildout script does not exist. Have you bootstrapped your system?")
  IOError: The bin/buildout script does not exist. Have you bootstrapped your system?

Note that the project was built of course ...

@andre.anjos, @amohammadi: Any fixes needed ? (could not find where to do it myself, sorry)
