I was lacking this file, so I downloaded and built the latest version of
bzip2.  I still get the same error message, which I don't understand,
namely:

    bzr: ERROR: exceptions.ImportError: failed to load bzrlib.repofmt.groupcompress_repo.RepositoryFormat2a: No module named bz2

Presumably "bzrlib.repofmt.groupcompress_repo" means the file
.../bzrlib/repofmt/groupcompress_repo.py, but what, exactly, is a "module
named bz2"?  What is its filename, where is bzr (or Python?) looking for
it?

I've tried, but failed, to submit a bug report for this.  The maintainers
of bzr use a tool called "Launchpad", which uses a gaudy log-in script
which breaks horribly on my ancient Firefox.  To submit a bug about
Launchpad, you've got to use, er, Launchpad.  Talk about sub-optimal
intelligence.  ;-(

I'd really like to get all this difficult stuff fixed so that I can get
back to something nice and easy like CC Mode.  ;-(

Here is the entire diagnostic from my attempt to run 'bzr init-repo .'.
Further help would be most appreciated:
