build fail of commercialhaskell.com with stack build on mac os x sierra

Hi,

git clone (commit dfe55e97ed86567aafca2e5f3c19096e2a4cb50f - Sep 20th 2016) of commercialhaskell.com from github:

https://github.com/commercialhaskell/commercialhaskell.com.git

follow instructions from that repo exactly for os x (stacksetup installed ghc-7.10.2, but i have seen similar issue with 8):

$ brew install icu4c
Add the following to your ~/.stack/stack.yaml:

   extra-include-dirs:
   - /usr/local/opt/icu4c/include
   extra-lib-dirs:
   - /usr/local/opt/icu4c/lib
Now:

   $ stack build

Hit one minor issue in build process with icu4c, resolving with following stack build:

stack build --extra-lib-dirs=/usr/local/opt/icu4c/lib --extra-include-dirs=/usr/local/opt/icu4c/include

reach build of yesod-auth, with a failure:

So reporting.... I've seen the same error attempting to brew install haskell-stack on sierra betas 3 and 4, but on those occasions, an issue with libghc_44.dylib causing the problem.
