Turn a non-repository into one

[Dj Gilcrease]

I have an odd situation. I have an app that has many existing users,
and I would like to be able to turn their current installs into a
repository that is based on mine. Currently their installs are raw (no
.hg directory at all) and I has hoping that "hg init" && "hg pull
MY_REPO" would just overwrite their existing files, leaving ones that
are not in the repo alone, but when I do that I get

rollback completed
Traceback (most recent call last):
  File "setup.py", line 238, in install
    self.installer.install()

    bins = [self._chunk(r) for r in xrange(base + 1, rev + 1)]

    return decompress(self._chunkraw(rev, rev))
  File "/usr/local/lib/python2.6/dist-packages/mercurial/revlog.py",
line 111, in decompress
    raise RevlogError(_("unknown compression type %r") % t)
mercurial.error.RevlogError: unknown compression type 'M'


Is there any way to achieve what I want or do I just need to make them
install a new version that comes with the .hg directory?
