'module' object has no attribute 'SIGWINCH' error on Bazaar-2.1.0-2 for OSX snow leopard

[Carl Youngblood]

I'm on OSX snow leopard running the built-in python 2.6. My PYTHONPATH
contains only /Library/Python/2.6/site-packages. After installing the
Bazaar 2.1.0-2 package, I get the following error when trying to run
bazaar:

Traceback (most recent call last):
  File "/usr/local/bin/bzr", line 141, in ?
    bzrlib.trace.enable_default_logging()
  File "/Library/Python/2.6/site-packages/bzrlib/trace.py", line 278,

    term_encoding = osutils.get_terminal_encoding()

    obj = _replace()

    obj = factory(self, scope, name)
  File "/Library/Python/2.6/site-packages/bzrlib/lazy_import.py", line

    module = __import__(module_python_path, scope, scope, [member])

    signal.signal(signal.SIGWINCH, _terminal_size_changed)
AttributeError: 'module' object has no attribute 'SIGWINCH'

Has anyone seen this before? Any ideas?

Thanks,
