[11:37:50] <+camelia> rakudo-moar 646b90: OUTPUT«===SORRY!===Cannot find

[11:38:19] <lizmat> mutli ?
[11:38:25] <FROGGS> tpyo
Expanding on this a bit more:
$ 6l 'role A { mutli method BUILD() { say "A" } }; class B does A { } }'
Cannot find method 'collisions'
at src/gen/m-Metamodel.nqp:2634 (blib/Perl6/Metamodel.moarvm:apply:69)
from src/gen/m-Metamodel.nqp:2812 (blib/Perl6/Metamodel.moarvm:compose:96)

from src/gen/m-Perl6-Actions.nqp:2161
(blib/Perl6/Actions.moarvm:package_def:1209)
It looks like $to_compose_meta in src/Perl6/Metamodel/RoleToClassApplier.nqp,
line 63 is not of a class that has a .collisions method (it *is* instantiated,
but as WHAT I have not been able to determine).
Compare this with the error where we just have the role definition:
$ 6l 'role A { mutli method BUILD() { say "A" } }'
Undeclared routine:
mutli used at line 1

One would expect the above code to do the same.
