DBD::myql 4.022 not passing test 80procs.t and how to FIX it

I failed to install DBD::mysql. This time I had the dev files and everything.

FAIL Installing DBD::mysql failed. See /home/pmg/.cpanm/build.log for details. $ cpanm DBD::mysql [...] DBD::mysql::db do failed: alter routine command denied to user ''@'localhost' for routine 'test.testproc' at t/80procs.t line 41.

Looking at this line of code:

my $drop_proc= "DROP PROCEDURE IF EXISTS testproc";

ok $dbh->do($drop_proc);

And looking at my mysql db table I can see that there is no privileges for alter or execute procedures

mysql> select * from db\G
                 Host: localhost
                    Db: test

FIXING the problem: Add permision to anyone from localhost to test

 mysql> grant ALL on test.* to ''@'localhost';
  mysql> show grants for ''@localhost;
