I've now managed to get it going. As I am a newbie with Drupal and not really an expert with PHP and MySQL either here a documentation for other dummies like me who might be facing similar issues with Liquid:
(with Drupal 4.7.2 on MySql 4.0)

1. Even though Liquid is a 4.7.0 module you have to install the tables manually via shell or PHPmyAdmin (as mentioned in the readme.txt)

2. Even if the installation looks successful you might get the following error message if you try to post your first Wiki page via create content:
Fatal error: Call to undefined function node_validate_tithttp://drupal.org/comment/reply/77321#comment_formle() in /var/www/html/market/modules/liquid/liquid_wikipage.module on line 73
In this case open the file liquid_wikipage.module and uncomment the line 73 (by putting '//' in front of it)

3. Create a Menu item (via adminster/menus). You might for example call it MyWiki. As a path to the Wiki define /wiki

4. Go to administer/input formats. Add a new input format. Give it a name, e.g. Wiki. Tick the roles that are supposed to use the Wiki and tick the Liquid MediaWiki Filter (Liquid implementation)

5. Go to create content and create your first wiki page, in my case: Wiki Start Page

6. Go to administer/settings/liquid. Set the default content type to wiki page and the default page to the name of your first wiki page, in my case Wiki Start Page.

That's it. Now you can go to your menu item MyWiki (or whatever you've called it). Edit your first entry and try to produce a link with square brackets: [[my first link]]
Liquid does not seem to accept WikiWords

Please post your comments and improvements and maybe this will develop into some kind of manual for Liquid.
