Would it be possible to get an updated version of your package that remedies these issues?—

GHC 7.10.1-rc1 isn't happy about control-monad-free-0.6.0.1
, I'm afraid:
Control/Monad/Free.hs:159:10:
Could not deduce (Alternative (FreeT f m))
arising from the superclasses of an instance declaration
from the context (Functor f, Monad m, MonadPlus m)
bound by the instance declaration
at Control/Monad/Free.hs:159:10-67
In the instance declaration for ‘MonadPlus (FreeT f m)’
GHC 7.8.4 issues the following warnings:
[1 of 3] Compiling Control.Monad.Free ( Control/Monad/Free.hs, dist/build/Control/Monad/Free.o )

More compiler warnings from GHC 7.10.1-rc1 that might be of interest:
on the commandline: Warning:
-XOverlappingInstances is deprecated: instead use per-instance pragmas OVERLAPPING/OVERLAPPABLE/OVERLAPS
from control-monad-free.
Thanks, that's very helpful. Version 0.6.1 is up with the missing
Alternative instances. If I can get around to download 7.10 then I'll sort
out the use of -XOverlappingInstances as well
