ruby still shows old version

Question

I have installed or I think is is so a new version of ruby on my osx ppc running leopard 10.5.8 but when I run ruby --version it shows the old one 1.8.7 (default on the machine) but when I run...

find /usr -type f -name \*.rb

it shows ruby2.0.o is on:

/usr/local/lib/ruby/2.0.0/

with all its .rb files.

But when I check using locate ruby

it shows the version 1.8.7 under

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

Anytime I check on ruby --version it shows the 1.8.7...how can I change that?

Totally newbie...thanks.

BTW rvm is not installing by anychance or homebrew and My xcode doesn't have downloads.

After running in circles trying to reinstall rvm and ruby, what did it for me was simply changing the default ruby version used by rvm:

Try running rvm list

In my case I had

=* ruby-2.1.1 [ x86_64 ]
ruby-2.1.4 [ x86_64 ]
ruby-2.2.2 [ x86_64 ]

After running rvm --default use 2.2.2, I had the correct ruby version:

ruby-2.1.1 [ x86_64 ]
ruby-2.1.4 [ x86_64 ]
=* ruby-2.2.2 [ x86_64 ]
