Please copy/paste the contents of your .bash_profile file here, preferably in a code block ( [ CODE]paste here[ /CODE] ).
Note, don't put spaces after the [ like I did, did that so it wouldn't actually do a code block. It should look like this:
Edit: Also, your $PATH has /Users/gordonwhite/.rbenv/shims: in it several times. It only needs to be there once (not that that'll hurt anything, but could slightly slow things down).
