[Koha] still looking for mysql @ localhost

[eric salayon]

guys,

   gud day!

   i just successfully installed KOHA but mysql is not residing on the
same pc. i'd tweaked some statements in the Install.pm (include -h
$hostname to every mysql and mysqladmin commands) to make it work. but
now, when im trying to search for a book, the system still looks @
localhost for the database. below is the logs:
