Can't install mercurial on Mac OS X 10.7

[Leendert Botha]

I am trying to install Mercurial on mac. I've tried installing from source, using easy_install and using macports. Every time I get the following error when running 'hg':

  File "/usr/local/bin/hg", line 38, in <module>
    mercurial.dispatch.run()
  File "/usr/local/lib/python2.6/site-packages/mercurial/dispatch.py", line 27, in run
    sys.exit(dispatch(request(sys.argv[1:])))
  File "/usr/local/lib/python2.6/site-packages/mercurial/dispatch.py", line 40, in dispatch
    req.ui = uimod.ui()
  File "/usr/local/lib/python2.6/site-packages/mercurial/ui.py", line 43, in __init__
    for f in scmutil.rcpath():
  File "/usr/local/lib/python2.6/site-packages/mercurial/scmutil.py", line 399, in rcpath
    _rcpath = osrcpath()
  File "/usr/local/lib/python2.6/site-packages/mercurial/scmutil.py", line 371, in osrcpath
    path = systemrcpath()
  File "/usr/local/lib/python2.6/site-packages/mercurial/scmutil.py", line 420, in systemrcpath
    path.extend(rcfiles(os.path.join(p, 'etc/mercurial')))
  File "/usr/local/lib/python2.6/site-packages/mercurial/scmutil.py", line 409, in rcfiles
    for f, kind in osutil.listdir(rcdir)
  File "/usr/local/lib/python2.6/site-packages/mercurial/demandimport.py", line 75, in __getattribute__
    self._load()
  File "/usr/local/lib/python2.6/site-packages/mercurial/demandimport.py", line 47, in _load
    mod = _origimport(head, globals, locals)
ImportError: dynamic module does not define init function (initosutil)

Any help would be greatly appreciated.
