- postinstall of the Mac OS X PKG failed as a parameter for 
   mysql_install_db was changed for MySQL 4.1
 - postinstall of the Server RPM failed as mysql_create_system_tables was
   missing from the file list


support-files/MacOSX/postinstall.sh:
   - Fix parameter for mysql_install_db (it was changed from -IN-RPM to --rpm
     in the 4.1 tree)
support-files/mysql.spec.sh:
   - Added missing file mysql_create_system_tables to the server subpackage
