If I do `echo $PATH` I get the following:

> /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/local/share/npm/bin:/usr/local/share/python:/opt/X11/bin:/Users/kh/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

This is in my ~/.zshrc file: 

>export PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/local/share/npm/bin:/usr/local/share/python:/opt/X11/bin:$HOME/.rvm/bin:$PATH

I've had to manually add /usr/local/etc... at the front of this file because homebrew was complaining.

I've searched for all possibles files (I know of) to find where $PATH is being built from. But  to no avail. These are

    ~/.bash_profile
    ~/.bashrc
    ~/.profile

Any suggestions.
