OpenDBX not loading in Pharo 3, due to FFI problems

I cannot manage to load ConfigurationOfOpenDBX in 3.0 due to FFI not loading (ShortRunArray in initialize of a class, replacing it with ShortIntegerArray let me pass).

But then, failures.

I am using the Pharo2 compatibility metacello trick which lets me load 2.x configs in 3.x
(Load this setting in a 3.x from here: http://www.smalltalkhub.com/#!/~philippeback/HOExtras/packages/Settings-Metacello)

Clues?
