>Description:
hellanzb.py does not function properly when built from ports.  It seems the version from ports has a string comparison bug in /usr/local/lib/python2.6/site-packages/Hellanzb/HellaReactor.py.  I have attached a very simple fix to this bug report that should correct the problem.
>How-To-Repeat:
1. Install news/hellanzb from ports.
2. Try to run it: `hellanzb.py`.

You will see:
$ hellanzb.py
/usr/local/lib/python2.6/site-packages/twisted/internet/default.py:15: DeprecationWarning: twisted.internet.default is deprecated. Use posixbase or selectreactor instead.
  warnings.warn("twisted.internet.default is deprecated. Use posixbase or selectreactor instead.", category=DeprecationWarning)

    from twisted.internet.default import _NO_FILENO
ImportError: cannot import name _NO_FILENO

>Fix:
Here is a simple one-line fix for the problem:
