Subject: 23.0.60; Emacs don't see $PATH
Date: Fri, 12 Dec 2008 01:54:51 +0300

Emacs don't see $PATH environment variable.

Step to reproduce bug:

(setenv "PATH" (concat "/opt/local/bin:" (getenv "PATH")))
(getenv "PATH") ;; => "/opt/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
(shell-command-to-string "which git") ;; > /opt/local/bin/git
(git-status) ;; produced the error

backtrace:
  Debugger entered--Lisp error: (file-error "Searching for program"  
"No such file or directory" "git")
  call-process("git" nil t nil "rev-parse" "--show-cdup")

It doesn't work like that. call-process uses the Lisp variable
exec-path, which is set at startup based on the value of $PATH.
So you should be adding /opt/local/bin to exec-path, or to PATH before
you start Emacs. Changing PATH after Emacs has started will not affect
call-process and similar things.

(There may be a separate issue with --with-ns and environment, bug#1333.)

This is not a bug: setenv changes the value of PATH passed to the
child processes, but not the value Emacs itself uses to search for
executable programs.  In your case, had Emacs found and invoked `git',
it would have passed `git' the value of PATH that included
"/opt/local/bin".
