Controller cant find my RMagick installation on OSX 10.4

I need to install RMagick as it is a required dependency for the
file_column plugin which I am trying to use.

I was completely baffled by the instructions on by the RMagick website
for installing RMagick on OSX.

However, I found these alternative instructions which come from the same
chap who provided the instructions for installing RoR on Tiger.

So I did all of that and now I think I have RMagik installed in

In my application when I have a require ‘RMagick’ I get an error - no
such file to load – RMagick

Seems RoR doesn’t know its installed…
what have I missed?
