Scripted install trouble

hello, i trying scripted install

./install_amp --debug --scripted --uid=asterisk --gid=asterisk --asteriskuser=admin --asteriskpass=myamppass --username=asteriskuser --password=mydbpass --set-freepbx-settings --force-overwrite


Checking for PEAR DB…OK
PHP Warning: date_default_timezone_get(): It is not safe to rely on the system’s timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘America/New_York’ for ‘EDT/-4.0/DST’ instead in /usr/src/freepbx-2.11.0/amp_conf/htdocs/admin/libraries/utility.functions.php on line 76
Checking for PEAR Console::Getopt…OK
Console_Getopt: unrecognized option --asteriskuser

what i may change AMI password at install?

What version of FreePBX?
