strange crash checking status

[Adam Mercer]

Hi

I am having a strange problem in one of the subdirectories within one
of my repositories. I get the following error when checking on the
status, ie:

[ram at skymoo ligolw]$ bzr status
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "/opt/local/bin/bzr", line 21, in ?
    import os
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/os.py",
line 683, in ?
    import copy_reg as _copy_reg
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/copy_reg.py",
line 7, in ?
    from types import ClassType as _ClassType
ImportError: cannot import name ClassType

I get the same error using both 0.14 and 0.15.  Any idea to what could
be causing this?

Cheers

Adam
