Basic *nix Question (Mac OS X): Where is my path being set?
Solution 1:
Stuff like this can be set on a per-user basis in which case you should be able to find something in your .bashrc, .bash_profile or .profile files. Or it can be set on a global level. In that case, I'd take a look inside /etc/environment, /etc/profile and /etc/bash.bashrc.
