[Radiant] Error creating my first Radiant project

[Maik]

Hi,

I just installed Radiant on Debian 6 via Gems.

When I execute "radiant --database mysql ~/test-project" radiant stops
with the following error:

WARNING:  Invalid .gemspec format in '/var/lib/gems/1.8/specifications/
radiant-1.0.1.gemspec'
/usr/lib/ruby/1.8/rubygems.rb:779:in `report_activate_error': Could
not find RubyGem radiant (>= 0) (Gem::LoadError)
        from /usr/lib/ruby/1.8/rubygems.rb:214:in `activate'
        from /usr/lib/ruby/1.8/rubygems.rb:1082:in `gem'
        from /var/lib/gems/1.8/bin/radiant:18

Any idea what is wrong?

I am running Ruby 1.8.7 and rails has version 2.3.14. However, just
running rails gives me the same error about the radiant-1.0.1.gemspec
as above.

Thanks,
-Maik
