Unable to run civicrm_generated.mysql query

Hi:

I've trying to install CiviCRM without succes.
I'm running Drupal 4.7.2 on MAMP (Apache 2.0.55, MySQL 5.0.19 and either PHP 4.4.2 or PHP 5.1.2)

I've downloaded from www.openngo.org both the PHP4 and PHP5 versions for Drupal (civicrm-drupal-php5-v1.4-rev6012M.tgz)
I've created a new database for CiviCRM and I could run the provided civicrm_41.mysql script.

But when I continue, according with the installation instruccions with either civicrm_generated.mysql or civicrm_data.mysql I get errors while importing.
I'm using phpMyAdmin for doing the import.

Has anyone managed to install using these scripts?

Thanks in advance!
