[chef] during chef-server install, no pkgs for libfog-ruby or chef-expander

hi,

i followed the server install instructions in
http://wiki.opscode.com/display/chef/Package+Installation+on+Debian+and+Ubuntu

it looks like it worked, at least in that most services are present
and running with no errors. the instrux say to install libfog-ruby
(optional) and chef-expander. but apt-get finds no packages for those.
and so the "verify all components are running" step fails because i
have no chef-expander.

where do i find these packages? i figure i can install libfog-ruby
via gem. but, are there debs?

thanks,
kallen
