Forum: Radiant CMS Superclass Error in 0.80 Install

I'm upgrading from 0.7.1. And following the unstructions on the blog, I
ran

gem install radiant
rake radiant:update

but then...

rake production db:migrate

gives an error:

[ps7899]$ rake production db:migrate --trace
(in /home/)
** Invoke production (first_time)
** Execute production
** Invoke environment (first_time)
** Execute environment
rake aborted!
super: no superclass method `require'
/home/.gems/gems/radiant-0.8.0/vendor/rails/activesupport/lib/active_support/dependencies.rb:158:in
`require'

Does anybody know the cause?

Cheers,

Ben

Sorry for the typos; it seems that I rushed that last message a bit.

Should have been:

*instructions
*Radiant 0.8.0

The problem was in my HAML plugin.
