[phenixbb] phenix.refine command line

Hi guys, I'm just trying to install phenix on a students new macbook pro running OS10.8.2, and want to get phenix.refine working on the command line. I've put in: alias setphenix="source /Applications/PHENIX-1.8.1-1168/Contents/phenix-1.8.1-1168/phenix_env.sh" in the .bashrc which seems to execute OK (and already pointed the .bash_profile to .bashrc) however whenever I then type phenix.refine I get command not found. As this is the same setup that I have running on my own machine I am a bit confused as to what is happening! Thanks! Simon
