Backgroundrb devel - Dec 2008 - backgroundrb won''t start after upgrade

Hello,
I just upgraded BackgroundRb on a working Rails app by checking out
the newest code from the git repository, deleting anything in the
scripts directory left by the old version and running rake:backgroundb
setup. It now appears to be horribly broken and the server won''t
start. For example:

bonnacon% script/backgroundrb start
[SNIP]/vendor/plugins/backgroundrb/lib/backgroundrb/bdrb_config.rb:6:in
`parse_cmd_options'': uninitialized constant
BackgrounDRb::Config::OptionParser (NameError)
        from script/backgroundrb:15

Adding a "require ''optparse''" instruction to the
code mentioned above
leads to this error instead:

bonnacon% script/backgroundrb start
/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.2/lib/active_support/dependencies.rb:493:in
`const_missing'': uninitialized constant
BackgrounDRb::MasterProxy::BDRB_CONFIG (NameError)
        from
/home/milo/Work/Web/cpdnresults/vendor/plugins/backgroundrb/server/lib/master_proxy.rb:7:in
`initialize''
        from script/backgroundrb:42:in `new''
        from script/backgroundrb:42

Is this an error with my Rails setup (2.2.2), or is there something
wrong with BackgroundRb itself?
Thanks,
Milo.
