ActiveRecord\MysqliAdapter not found!

[zeekerg]

My MAMP is running Php 5.4.4.

I successfully managed to install Bonfire(latest) with Sparks to use PhpAR.

I've pre loaded the php-activerecord library in the config and works really well.
When I run a simple query like User::all(), this error appears even though my default driver in my config is 'mysql' (not mysqli).
