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.)
