ah, my bad I thought I'd included that -- this is ghc 7.8.3, on MacOS, installed from https://ghcformacosx.github.io ... 

Should I just move to 7.10?

What ghc version and how was it built?

Hi all,

I cannot build 'vector' (or 'cmdargs') with profiling on. 

specifically when I run:

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

I get the message:

    Perhaps you haven't installed the "p_dyn" libraries for package ‛integer-gmp’

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

Per some advice I tried to add the '--disable-shared' 

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

but then I get this:

    Loading package primitive-0.6 ... <command line>: can't load .so/.DLL for: libHSprimitive-0.6.dylib (dlopen(libHSprimitive-0.6.dylib, 9): image not found)

Any idea whats going on or for any work arounds? Pretty stumped! Thanks in advance!
