Sorry for not providing basic information above.  I use Debian,
including Debian's version of emacs 21.3 and ipython 0.6.5, but my own
(newer) versions of ipython.el, python-mode.el and ansi-color.el.

If I do "emacs -q" and then `M-x term', everything is fine.  "ls
--color" produces color output, and ipython works fine in that
terminal, with color.

If I do "emacs -q" and then 
`M-x load-library RET /home/jdc/emacs/lisp/ansi-color.el RET 
 M-x ansi-color-for-comint-mode-on
 M-x shell'
then again everything works fine (except that a few control characters
in my prompt show up in the buffer).

If I do "emacs -q" and eval

(setq load-path 
      (append (list "~/emacs/lisp"    
		    "~/emacs/python-mode"
		    )
	      load-path))
(require 'ipython)

and then `C-x C-f /tmp/test.py RET' and `C-c C-c', I get no color at
all in the *Python Output* buffer, just lots of control characters.
Also, ansi-color-for-comint-mode's value is nil.  If I manually
run ansi-color-for-comint-mode-on, and then do `C-c C-c' again,
there is no change.

Let me know what other information would be useful.

Thanks,

Dan
