Unable to upgrade to aegir beta 12. drush hostmaster-install fails. there is a weird "site_test" variable

I got the following if I let the full install run: "Unable to create new databases."

1. I have followed the directions
2. I have run as aegir
3. Three entires for aegir_root for my fully qualified domain, the ip address, and localhost are created with the random password created by the install script.
4. tested this command and I can connect to the mysql database with the password generated
mysql -raegir_root -p -h 'uname -n'

4. I tested and it was the last line in the install script which installs the frontend which causes this error because the back end installs fine.

$DRUSH hostmaster-install --aegir_host=$AEGIR_HOST --aegir_db_user=$AEGIR_DB_USER --aegir_db_pass=$AEGIR_DB_PASS --version=$AEGIR_VERSION

I continued testing

1. tested just drush hostmaster-install
I thought it strange that it says using password when in fact I was not.

su -s /bin/bash aegir aegir@devhost:~$ drush hostmaster-install
Aegir domain name [aegir.example.com]: aegir.somesite.com

2. tested "drush hostmaster-install --aegir_host=aegir.somesite.com"
I thought it strange that it still asked me for the Aegir domain name even though I defined the variable and no password was given yet it says "using password:YES"

aegir@devhost:~$ drush hostmaster-install --aegir_host=aegir.somesite.com
Aegir domain name [aegir.example.com]: aegir.somesite.com

3.
a) I ran the command with a password
b). at line 315 I placed a print_r($args);
before the original line at 315 to see what was going on

return substr($this->conn->quote(array_shift($args)), 1, -1);

c). I noticed "site_test" was the value printed. Shouldn't this be the aegir_root?

drush hostmaster-install --aegir_host=aegir.somesite.com --aegir_db_pass=0a7f601c75605506fb07f807ae1ac4ee

4. finally when I run the entire command with -verify I get the same thing
