Upgraded and moved Rubies, now can't load

[trans]

I upgraded to the last version, but I also move my rubies from /opt/Ruby to ~/.rubies, now I get:

<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
    from <internal:gem_prelude>:1:in `<compiled>'
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
    from <internal:gem_prelude>:1:in `<compiled>'

I'm thinking it might have to do with the fact that I moved my rubies from /opt/Ruby to ~/.rubies, but chruby doesn't seem to completely know it. When I try irb I get:

$ irb
bash: /home/trans/.rubies/1.9.3-p327/bin/irb: /opt/Ruby/1.9.3-p327/bin/ruby: bad interpreter: No such file or directory

Yea, okay. So when installing the Ruby it uses --prefix which, it appears, locks it into a specific path and it can't be moved.

Yep, you will have to change the #! lines, as they are hardcoded for MRI.
