Yeah, make sure you have that module installed, as well as:

server.pl should die if it can't load a module, although that code may 
only be in place for controllers with compilation errors.

There's the root of your problem, although I've never seen this error 
before.  The database is read using DBD::SQLite2, which is a complete 
implementation of SQLite 2 in a module, it doesn't depend on a system 
install of sqlite.  Maybe you just need to upgrade that module?

If that doesn't work you can try rebuilding the db file, although this 
will require you to install sqlite 2.x on your system:
rm -f ServerDB.db; sqlite ServerDB.db < ServerDB.sql

Make sure you aren't using sqlite 3, because I think it's not compatible.
