You should be able to use your new ruby by its full path name:

$ /opt/local/bin/ruby  --version
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-darwin9]

To make that the Head Ruby In Charge, try this:

echo 'export PATH="/opt/local/bin:$PATH"' >> ~/.profile
export PATH="/opt/local/bin:$PATH"
hash -r

You should then see the right ruby by default:

$ which ruby
/opt/local/bin/ruby
