Comment (by ctreleaven):

 I may have found a solution.  It appears that appending
 {{{-DBoost_INCLUDE_DIR=""}}} to the configure args prevents an installed
 boost from being found.  Not the cleanest solution but the resulting lib
 no longer references {{{libboost_atomic-mt.dylib}}}.

 Relevant portion of the configure output is:


 {{{
 -- Could NOT find Boost
 -- Performing Test HAVE_STD_ATOMIC
 -- Performing Test HAVE_STD_ATOMIC - Failed
 CMake Warning at /opt/local/share/cmake-3.7/Modules/FindBoost.cmake:761

 I can commit this if you like.
