missing import in compilemessages

[yml]

To put it in a nutshell someone should add :
from django.core.management.base import CommandError
At the top of the file called "compilemessages.py"

Traceback :

django-survey\examples>django-admin.py compilemessages  --setings="examples.settings"
Usage: C:\yml\_myScript_\dj_things\web_development\svn_views\external_libs\django\bin\django-admin.py compilemessages [options]

Compiles .po files to .mo files for use with builtin gettext support.
