I was having this problem a month or so back while running some scripts
that executed other extermal programs. (I am using latest homebrew zsh in
tmux in Mountain Lion but I think that is immaterial in my case). I can't
remember specifics but I just did some searches in my system. I use
zpresto. It contains a file: runcoms/zshenv which i think is what was
resetting my path. I believe I corrected the order there and now things are
working.

There's a line starting with : path=(
You can search for that in your system and see if this has any relevance to
your problem.
