I'm trying to run a console script from my crontab but I'm getting a
console error.  It works fun when I run it from the command line.  I'm
guessing there's an environment variable I need to set but what is it?
Anyone have any advice?

I'm calling it like this:
/Users/alex/links/script/console production < /Users/Alex/links/digg.rb

And getting this error:
/usr/lib/ruby/1.8/irb/completion.rb:10:in `require': No such file to
load -- readline (LoadError)
        from /usr/lib/ruby/1.8/irb/completion.rb:10

look into script/runner.  It is meant to do these sorts of things...

So...

say you have RAILS_ROOT/lib/foo.rb:

class Foo
   def self.foobar
     #do your stuff here
   end
end

you could then do:

RAILS_ROOT/script/runner "Foo.foobar" -e production

What's nice is that you can use any of your models class methods as
well...
