[koha] installing with script installer.pl

[Gerard Henry]

hello,
first installing koha with script installer.pl on a solaris 8 machine, everything went fine, until this:
 CREATING DATABASE 

Creating the MySQL database for Koha...
/usr/local/mysql/bin/mysql  Ver 11.16 Distrib 3.23.49, for sun-solaris2.8 (sparc)

blabla...

 ERROR CREATING DATABASE 

It sounds like arguments are wrong, but how can i control it? i verify i can log in my db:
machine-root% mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 11520 to server version: 3.23.49-log

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> 

If anybody can help?

Thanks in advance,
