There may be two bugs, but they both seem to be in the same category.

I've not tried it, but I'm going to take your word for it.  I'm a bit  
busy right now to investigate in detail.

Can you poke around in setup.rb to see if its ignoring --prefix?

You can install your own ruby in your homedir, then it'll work.

Right now it appears to be using Ruby's prefix over the one you  
want.  If you have your own ruby, you'll be able to write to where  
setup.rb is trying to put things.

Poor workers blame their tools. Good workers build better tools. The  
workers get their tools to do the work for them. -- Syndicate Wars
