Build on OSX Sierra fails

[Horsmann]

Hi, I tried to build the hunpos binaries for OSX using the provided build script. I get this error:

Finished, 1 target (0 cached) in 00:00:00.
/usr/local/lib/ocaml/libasmrun.a

Exit code 2 while executing this command:

Any idea how to fix this?

Try using gnu sed instead of the bsd sed that follows with os x. It can be installed with brew install gnu-sed and added to the path by setting PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH.

Thanks. Works with gnu-sed.

Another option is to upgrade ocaml to 4.02 version. I think it would be nice to fix the sed command line so that it works with both gnu sed and bsd sed.
