voila ce que j ai:
dans le jeux sur longlet language:
Freeciv supports several local languages. See the Native Language
Support section of the README file for instructions on how to use
one of these languages.
If you would like to add a localization (translation) for your
language, please see the instructions at:
http://www.freeciv.org/index.php/Localization
Check first if a localization is already in progress for your
language:
http://www.freeciv.org/index.php/Translations
You are also welcome to send any questions to the freeciv-i18n
mailing list:
freeciv-i18n@freeciv.org

et dans read me:

If you want to use American English, do nothing. Otherwise, you can activate Freeciv's localization support via a couple of ways. The game launchers look to the following, in the order listed, for a language to use:

1. User default. Via the Terminal, you can set the locale for either game client launcher via the following:

% defaults com.saltybanana.FreecivClient.GTKn write locale xxx

where n is either 1 or 2, and xxx can be either a two-character or five-character code. To see the current setting, do this:

% defaults com.saltybanana.FreecivClient.GTKn read locale

To clear the setting, simply delete the com.saltybanana.FreecivClient.GTKn.plist file from your account's Library/Preferences folder.

2. International Preference Pane. Each game launcher will scan the languages listed in this preference pane and look for the first one that is supported by Freeciv.

3. The LANG environment variable. This value must be 5 characters long. If the code (see above) for your language of choice is only two characters long, append _XY to it, where XY are the upper-case letters of the language code.

For example, to use Spanish, do this:

% setenv LANG es_ES

To use British English, do this:

% setenv LANG en_GB

If you choose this option, you probably need to set the environment variable and then open the game client launcher via the terminal. For example:

% setenv LANG es_ES
% open "/Applications/Games/Freeciv 2.0.3/Freeciv Client (GTK2).app"

Of course, you can also configure your shell to have the environment variable set every time you login
