What version of Loader is that using (and what version of
DBIx::Class)?  I wouldn't expect such an error out of Loader 0.14+,
but if it is, I guess we need some more fixes.  One known issue is
that Loader doesn't handle multi-column FKs very elegantly or
correctly (or multiple rels between the same pair of tables), but it
has never done so.  FWIW Schema::Loader does the multi-col FKs
correctly.
