e.g.,
$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/bin:~/bin:/usr/local/Cellar/python3/3.2.3/bin
$ vim
:! echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:~/bin:/usr/local/Cellar/python3/3.2.3/bin
I expected them to be the same. Why are they different?
If it makes a difference, here is my shell, vim version and OS version:
$ echo $SHELL
SHELL=/usr/local/bin/zsh
$ /usr/local/bin/zsh --version
zsh 5.0.0 (x86_64-apple-darwin12.0.0)
$ vim --version

This is a known problem introduced by Apple in OS X 10.5 Leopard.
If you are using Bash or Zsh and are using non-interactive shells, you are affected.
Running
sudo chmod ugo-x /usr/libexec/path_helper
will fix you up, but you should take a look at the article to see why.
From this SO answer
There are many similar questions on stackoverflow and stackexchange.
Your shell executes different *rc files depending on the arguments its given at launch time. Therefore, you need to setup Vim so that it launchs your shell with the right arguments.
The following helps in bash, I'm almost certain there's a similar flag in zsh.
set shell=bash\ -i
See $ man zsh
for the right flag and the right execution order.
