Hello all, I have been trying to build PyXPCOM against xulrunner for some
time.  I think the build environment in all it's complicated glory was
making it difficult for me.  I tried mozilla-build today, and that seems to
be working well.  I built with 1.9a2pre... anyway, I get this error:

> >> import xpcom.components
Traceback (most recent call last):
  File "<stdin> ", line 1, in <module>
  File "xpcom\components.py", line 231, in <module> 
    import shutdown
  File "xpcom\shutdown.py", line 51, in <module> 
    class _ShutdownObserver:
  File "xpcom\shutdown.py", line 52, in _ShutdownObserver
    _com_interfaces_ = interfaces.nsIObserver
  File "xpcom\components.py", line 103, in __getattr__
    return self._get_one(attr)
  File "xpcom\components.py", line 153, in _get_one
    raise xpcom.COMException(nsError.NS_ERROR_NO_INTERFACE, "The interface
'%s' does not exist" % (name,))
xpcom.Exception: -2147467262 (-2147467262)

does anyone know how to solve this?  or whether this is indicative of a bad
build, or just a bad environment?

Thanks,
Michael
