cannot build 'vector' with profiling

[Ranjit Jhala]

Hi Carter,

OK, here's the full info (see log below), this is on an MBP,
running ghc 7.8.3 (From ghcformac).

In a new directory, I create a FRESH cabal sandbox, and then do:

   $ cabal install --enable-library-profiling --ghc-options="-O2 -rtsopts
-prof -auto-all -caf-all" vector

In doing so I get errors about unable to build 'primitive' because

    Failed to load interface for ‘GHC.Integer.Type’
    Perhaps you haven't installed the "p_dyn" libraries for package
‘integer-gmp’?
    Use -v to see a list of the files searched for.

Googling the above takes me to

    https://ghc.haskell.org/trac/ghc/ticket/8677

But unfortunately I can't from the above tell exactly how to proceed.

1. Can you tell me how to get a profiling version of vector built in
   a new sandbox? i.e. what options are you using?

2. Is there any other information you need? I'm assuming since its in
   a sandbox I needn't nuke my global cabal directory but happy to if
   needed.

Thanks! (log below)
