proxy-server won't start

I'm trying a SAIO installation on Ubuntu Server 10.4. When running startmain, I get the following exception in python. I checked my .conf file and its identical with the exception of the user name of course. There is nothing in syslog or in the proxy specific log file at all.

Traceback (most recent call last):
 File "usr/local/bin/swift-proxy-server", line 7, in <module>
   execfile(__file__)
 File "/home/amarcionek/swift/bin/swift-proxy-server", line 22, in <module>
   run_wsgi(conf_file, 'proxy-server', default_port-8080, **options)

I'm omitting a bunch of lines here, but the last few seem interesting to me.

File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 546, in resolve
   raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: swifth

Anyone know what is wrong?

Thanks!
