Orca under Debian Unstable

[Jason White <jasonw ariel its unimelb edu au>]

Has anyone managed to run Orca successfully under Debian Unstable?

I get the following error:

[/tmp jdc]$orca --setup
Traceback (most recent call last):
  File "/usr/local/bin/orca", line 30, in ?
    import orca.orca
  File "/usr/local/lib/python2.4/site-packages/orca/orca.py", line 45, in ?
    import atspi
  File "/usr/local/lib/python2.4/site-packages/orca/atspi.py", line 48, in ?
    ORBit.CORBA.ORB_init(orb_id="orbit-io-thread")
TypeError: ORB_init() takes no keyword arguments
[/tmp jdc]$
This is Orca 0.2.6. Perhaps an autoconf entry is necessary to detect this at
configuration time.
What version of Python Orbit do I need, and is it available as a Debian
package?
