Hi,
I know this is an old problem, but I still couldn't figure it out with the tricks I found.
I work with the emacs 23.3 on Mac OS X 10.7.2 (Lion), installed from http://emacsformacosx.com/
When I open a shell with M-x shell and type echo $PATH, I get:
/usr/bin:/bin:/usr/sbin:/sbin
When I do the same in Mac's Terminal, I get:
/Applications/Emacs.app/Contents/MacOS/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin:/opt/local/bin:/opt/local/sbin
Question: How do I get the same PATH in emacs than in the terminal?
Trials:
1) fixpath.el:
(add-to-list 'load-path "~/.emacs.d/fixpath"); see https://svn.fsg.ulaval.ca/svn-pub/vgoulet/emacs-modified/macos/tags/Emacs-23.3-modified-3/fixpath.el
(require 'fixpath)
2) emacs wiki (http://www.emacswiki.org/emacs/EmacsApp#toc2)
;; add "defaults..." to /etc/profile:
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
defaults write $HOME/.MacOSX/environment PATH "$PATH"
fi
;; add the following to .emacs:
(add-to-list 'exec-path "/usr/bin")
3) another solution posted on the emacs wiki page:
;; read in PATH from .bashrc (and add at least those directories)
;; see http://www.emacswiki.org/emacs/EmacsApp#toc5
(if (not (getenv "TERM_PROGRAM"))
(setenv "PATH"
(shell-command-to-string "source $HOME/.bashrc && printf $PATH")))
Cheers,
Marius

I did not download the emacs that you did and dig around so I am sorta half guessing.
Recently while dinking with rvm, I discovered that bash is not being started with --login.
Since the M-x shell has fewer parts in its path, I would suspect that the additional
paths are being specified in /etc/profile. Without bash thinking it is a login shell,
/etc/profile is not being sourced. One way is to start it with a - as the first character in
arg0. The other way is to start it with --login.
To explore if this is right: find where the parts for longer path are being set. One
choice is /etc/profile, another is your ~/.profile. If these parts are in the profile but
not in your .bashrc, then we are likely on the right track.
If that is the case, then review explicit-bash-args. You can customize them and add --login
see if that works. I'm a bit surprised this isn't done in the stock version of the code.
If you have a .profile,.bash_profile,
or .bashrc, you can echo the path at the very top of each and open a new term window. This will
tell you where / how PATH is being set as it goes through your sequence of login scripts.
Hope this helps,
pedz

Dear Perry,
thanks a lot for helping.

sorry, I should have put this in earlier. So here is my /etc/profile [you still see the defaults write... from one of my trials]:
### /etc/profile ###
# System-wide .profile for sh(1)
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
defaults write $HOME/.MacOSX/environment PATH "$PATH"
fi
if [ "${BASH-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc
fi
###############
Here is ~/.profile [the last export is to call the same emacs when typing "emacs" in the Mac's terminal; otherwise, the preinstalled (old) emacs version is called]:
### ~/.profile ###
[ -f ~/.bashrc ] && . ~/.bashrc;
# MacPorts Installer addition on 2011-09-30_at_10:26:19: adding an appropriate PATH variable for use with MacPorts.
export PATH=$PATH:/opt/local/bin:/opt/local/sbin
# Finished adapting your PATH environment variable for use with MacPorts.
# make /Applications/Emacs.app/Contents/MacOS/emacs available when calling "emacs"
export PATH=/Applications/Emacs.app/Contents/MacOS/:$PATH
###############

My .bashrc only contains some aliases and export LC_CTYPE=en_US.UTF-8

Thanks for the hint!!! I found this (see http://www-stat.wharton.upenn.edu/~buja/STAT-540/.emacs):
(setq explicit-bash-args (list "--login" "-i"))
I put it into .emacs and started emacs again. M-x shell now shows precisely the same PATH as in the terminal.
The only thing I'm wondering is: If this is really the perfect solution, why is it not mentioned on http://www.emacswiki.org/emacs/EmacsApp ? It seems to be much simpler than the other solutions posted, and (as I wrote) the other solutions even did not work for me.
Cheers,
Marius

Yea. I bumped into this recently. I'm surprised that it does not kick off the shell using "-sh" as argv[0] since some shells *only* grok that method of starting a login shell.
I guess the emacs developers do not see *shell* as a "login" shell.
LIke you, I'm surprised.
