It's probably MacTeX which is a Mac-specific version of TeX Live.

Unfortunately, setting environment variables on a Mac is non-trivial,
probably because most GUI apps don't need any special environment.
See any of the many questions on stack overflow. e.g.
http://stackoverflow.com/questions/7501678/set-environment-variables-on-mac-os-x-lion

FWIW I call `launchctl setenv ...` in my .bashrc for certain variables
if their value doesn't match what I see from `launchctl getenv ...`
