[KDE/Mac] Building kactivities (Boost failure)

[Allen Winter]

Apologies if this has been discussed before.
I'm trying to build on my Macbook OSX 10.9, clang version 5.0, with kdesrc-build.

I got as far as kactivities, which is failing as follows:
In file included from /usr/local/include/boost/range/concepts.hpp:19:
/usr/local/include/boost/concept_check.hpp:168:5: error: non-type template argument refers to function 'failed' that does not have linkage
    BOOST_CONCEPT_USAGE(CopyConstructible) {
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/local/include/boost/concept/usage.hpp:29:7: note: expanded from macro 'BOOST_CONCEPT_USAGE'
      BOOST_CONCEPT_ASSERT((boost::concepts::usage_requirements<model>)); \
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/local/include/boost/concept/assert.hpp:43:5: note: expanded from macro 'BOOST_CONCEPT_ASSERT'
    BOOST_CONCEPT_ASSERT_FN(void(*)ModelInParens)
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


I have boost 1.57.0, cmake says min version required is 1.49

anyway, help.
