aspell dictionary path configuration

[Vincent Lefevre]

Hi,

I would like to know how to configure the dictionary path.
I currently get the following error:

Starting new Ispell process [francais] ...
ispell-init-process: Error: The file 
"/Applications/Emacs.app/Contents/Resources/lib/aspell-powerpc/francais" can 
not be opened for reading.

However, the French dictionary is installed somewhere else. I've
tried the following lines in my .emacs, but they don't seem to have
any effect (I still get the same error):

(setq ispell-program-name "/opt/local/bin/aspell")
(setq ispell-aspell-data-dir "/opt/local/lib/aspell-0.60")
(setq ispell-aspell-dict-dir "/opt/local/share/aspell")

What should I do?

Note: I use GNU Emacs 22.1.50.1 under Mac OS X, obtained here:
http://www.apple.com/downloads/macosx/unix_open_source/carbonemacspackage.html
It comes with its own aspell in /Applications/Emacs.app/Contents/MacOS/bin
and its own English dictionaries, but I want to use the dictionaries
that have been installed at the above paths (/opt/local/...).

TIA for any information,
