hi i tested openapoc run normally on mac(10.9.4). we need a two step. 1. dependencies install using brew 2. modify CMakeLists.txt add library 'allegro_main' because compiler cannot find '_al_mangled_main' on mac, clang++ so occured linking failed.. after modify cmakelists i tested mac and ubuntu 12.04. i created pull request. please check and test. thank you.
