 > * If you install a Haskell package to be used with GHC, you still need
 the `-dev` version of any C library dependencies.  That's independent of
 your proposal in comment:16, because we need the -dev libraries when
 building standalone executables.
 Is the C library going to be a static (archive) or da dynamic (shared
 object) library?

 If it is the latter then I think it would still work with comment:16 and
 if we pass a linker flag (something along the lines of copy all  DT_NEEDED
 tags for C libraries from the dummy SO into the executable) the
 performance impact would be small.

 But in the completely static case you are right, the dev dependency is
 always required.
