Bug in *your* PYTHONPATH environment variable, now that I think about it. ;)

On my system:

    $ echo $PYTHONPATH
    
    $ mkdir foo
    $ cd foo
    $ touch token.py
    $ bzr version | head -1
    bzr (bazaar-ng) 0.7pre
    $ PYTHONPATH=. bzr version
    Traceback (most recent call last):
      File "/usr/bin/bzr", line 49, in ?
        import bzrlib.commands
      File "/usr/lib/python2.4/site-packages/bzrlib/commands.py", line 33, in ?
        from inspect import getdoc
      File "/usr/lib/python2.4/inspect.py", line 31, in ?
        import sys, os, types, string, re, dis, imp, tokenize, linecache
      File "/usr/lib/python2.4/tokenize.py", line 38, in ?
        COMMENT = N_TOKENS
    NameError: name 'N_TOKENS' is not defined

What's in your $PYTHONPATH?

Possibly bzr should be more robust about this.  (Or someone should fix Python to
only import standard library modules from the one place, e.g. by putting them
all in a 'stdlib' package...)

Of course svn isn't much better:

    $ touch libc.so.6
    $ LD_LIBRARY_PATH=. svn --version

<wink>
