Comment (by simonpj):

 I think this one is correct.  You have to use `-fallow-incoherent-
 instances` when compiling the '''instance declarations''', not in the
 client module that uses them.  This is supposed to be a feature: the
 library writer can control instances individually.

 I'll clarify the error message though.  Thanks.

 Simon
