As far as I understand it on their website [1], rvm modifies your PATH
variable to switch between different versions of a tool.

Please check to what typing ruby in your shell refers with the command
'which ruby'. I assume it returns something like
"/Users/foo/.rvm/rubies/ruby-1.9.3/bin/ruby" as explained on the
website. Also check where this symlink points to.

Please check again what 'which ruby' returns now and where the symlink
points to.

Running 'port' cannot modify the PATH variable of either the current or
any other terminal. So I don't see how MacPorts could be doing anything
that would modify the behavior here.

I assume rvm does not more than modifying PATH and setting up symlinks,
I did not find more documentation on that matter.
