Ruby install not being found properly?

Hello all, I'm confused. The following lines from my terminal window say it all: $ ruby -v ruby 1.8.2 (2004-12-25) [universal-darwin8.0] $ which ruby /opt/local/bin/ruby $ /opt/local/bin/ruby -v ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.10.1] I have Ruby installed correctly with MacPorts, I have my path set up correctly, but for some reason when I use: $ ruby it goes back to the original system version instead of the newly installed one! Any ideas? Thanks, Michael
