Backgroundrb devel - Apr 2009 - Error running server: Exec format error - packet_worker_runner

Hi All, I''ve been developing a rails app using the Bitnami RailsStack (
http://bitnami.org/stack/rubystack) and it has always worked as advertised.
That is until I have tried to get BackgrounDRB up and running. I have
followed the steps given on the plugin''s project page, each seems to
work. I
the plugin install works, I can generate workers etc, but when I start the
backgrounDRB server I get the following errors in the backgroundrb log file:
>>/Applications/rubystack-1.4-beta-1/ruby/lib/ruby/gems/1.8/gems/packet-0.1.14/lib/packet/packet_master.rb:116:in
`exec'': Exec format error - packet_worker_runner

`start''
>>    from script/backgroundrb:35
In my frustrations I created a rails project from scratch to make sure it
wasn''t something in my other code / setup, but I still get the errors.

Has anyone seen this type of error before? If you have and suggestions I
would love to hear them. I really want to get this plugin working as it is
perfect for multiple projects I am working on. BTW: I am running on MacOSX.

Thanks.

P.S: Thanks to all devs who created this plugin - although I am not up and
running yet it looks to be a most useful tool. Cheers.
