I think you probably just haven't recompiled enough stuff after adding 
the primop.  I can't tell immediately whether it's the compiler that is 
out of date, or an interface file in libraries/base.

To be on the safe side, you could 'make clean' in ghc/compiler and 
libraries/base, then rebuild both.
