This is required only for *export* from hg.

Bazaar stand-alone installer missed several python libraries, at least 
mercurial and hg2git libraries. If you look in the 
exporters/hg-fast-export.py script you can see the following imports:

from mercurial import repo,hg,cmdutil,util,ui,revlog,node
from hg2git import setup_repo,fixup_user,get_branch,get_changeset
from hg2git import 
load_cache,save_cache,get_git_sha1,set_default_branch,set_origin_name

Those libraries are not part of standalone installer, because it's kinda 
strange (weird?) to ship Bazaar DVCS with another DVCS inside, isn't it? 
Although we ship svn libs inside and nobody complains.

This is fundamental distinctive feature of *standalone* installers on 
Windows created with py2exe. There is workaround (although I'd recommend 
you using python-based version instead). I can explain that workaround 
if you really wish. But first I'll need to explain how imports of python 
libraries works in standalone installer  under the hood. Are you really 
want to hear all gory details?

To fix it in the next standalone installer build somebody should add 
mercurial lib and hg2git lib to dependencies of standalone bzr build.
