There seems to be an error in the code that assumes each site has the  
Tags plugin installed. So if you didn't install it, you'll see errors  
such what you quoted.

Now, the solution for you would normally be 'just install the Tags  
plugin' by using the install-plugin tool, until this is fixed.

However, you can't. The latest code also has a problem with plugins/ 
Tags/mysql_schema.sql so the plugin will install, but it's missing  
tables from the DB when the plugin install completes. Which has the  
consequence that it'll break your installed site.

The solution therefore is to patch that file, run a make install on  
the whole src tree, then run install-plugin, then restart httpd. (or  
wait till a fix is committed and a new T-tag is created and upgrade  
your cvs checkout to that tag - but who's got the patience for  
that?!? :)

Now, I don't know if my patch (see below) is technically correct  
because it adds an auto increment where there wasn't one. But once I  
applied this patch, I could successfully install the Slash::Tags  
plugin, and all errors went away and everything worked like a champ.  
And I'm guessing the t-tag you chose to checkout is fairly close to  
recent CVS-HEAD, so your checkout has the same problem.
