I am using osx 10.8.4 and has brew installed.

I followed the ruby/rvm installation instruction here:

rvm install 1.9.3
rvm use 1.9.3
rvm rubygems latest

It ran without issues and errors. When I checked the ruby version I got this:

$ ruby --version
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.4.0]

It isn't what I expected. Did RVM automatically install higher version of ruby?

Here is the rvminfo

are you sure rvm use 1.9.3 worked properly and there was no error displayed?

you can run this to be more sure:

rvm use 1.9.3 && echo "Got 1.9.3" || echo "Failed switching ruby!"
