_can_be_made_compatible_with Errors during Build

Hi, when upgrading by Moose I get a lot of errors like this :

t/300_immutable/007_immutable_trigger_from_constructor.t .......... Can't locate object method "_can_be_made_compatible_with" via package "Moose::Error::Default" at /usr/local/lib/perl/5.10.1/Class/MOP/Class.pm line 375.
BEGIN failed--compilation aborted at t/300_immutable/007_immutable_trigger_from_constructor.t line 13.
t/300_immutable/007_immutable_trigger_from_constructor.t .......... Dubious, test returned 9 (wstat 2304, 0x900)
No subtests run 

nevertheless, Moose installs (1.21), but is that anything I have to worry about ?
	
(System is ubuntu 10.04 LTS, Class::MOP is 1.12	 )
