Wow, I just learned that dbname= is optional in DBD::SQLite. I had to test that to believe it. And it is not even documented :)

my $dbh = DBI->connect ("DBI:SQLite:dbname=abc.db", $userid, $password
+, {
    RaiseError => 1,
    AutoCommit => 0,
    }) or die $DBI::errstr;

would be the documented and preferred syntax. (Not that that would solve your problem though)
