I installed mediawiki on my machine (FreeBSD, mysql3.something, 
php4.3) once successfully, then nuked it (removing the database).  
I then tried installing it again, but I get the following error 
message on screen: 
 
Sorry! The wiki is experiencing some technical difficulties, and 
cannot contact the database server. 
 
And the following in my apache logs: 
 
[Fri Mar 19 02:22:50 2004] [error] PHP Warning:  mysql_error(): 
supplied argument is not a valid MySQL-Link resource 
in /web/users/dkesh/wiki/includes/Database.php on line 196

I don't know why it's having trouble talking to the database, but I 
get the same error if I put in a non-existent database server.  I 
think the installer should give a more descriptive error message, if 
possible.

Unable to reproduce...
FreeBSD: 5.2.1
MediaWiki: 1.2.0rc4
PHP: 5.0.0b4
MySQL: 4.0.16

Never had trouble on my Mac either; PHP 4.3.2. I'll see if I
can find an
MySQL 3 to check against...
