Considering that the GHC FFI is already built on libffi (I'm reasonably
sure) it seems unnecessary for the Hackage library to depend on an external
version. Is it not already getting linked in?

The scenario is pretty simple. I generate C code at runtime. I compile it

I get a FunPtr back from 'dlsym'. How do I call it?
I was hoping there would be some Raw lower level

Anyway, in this case it wasn't *too *painful to just generate a bunch of
extra boilerplate C functions for (1) creating a data structure to hold the
arguments, (2) loading them in one at a time, and (3) deallocating the
structure when the call is done.
