Radiant install problems

Hi all

I’m trying to install Radiant, but got stuck. Perhaps this might be a
more general Ruby problem, but I thought this might be the first place
to ask anyhow.

I’ve created the database (just a production one for now), but when
trying to run
% rake production db:bootstrap
I get the following error:
rake aborted!
undefined method `namespace’ for main:Object
/var/lib/gems/1.8/gems/radiant-0.6.1/Rakefile:7

Now, this line says:
require ‘tasks/rails’

Someone had a vague feeling that this may be due to some Ruby
environment variable not being set up properly to define what or where
available stuff is.

This is running on Debian/sarge and I had to install a backports version
of Ruby, so presumably there may be some glitch in the installation.

Thanks for any advice,
