io_splice для OSX EL Капитан ошибка

Я пытаюсь установить драгоценный камень в OS X !. Я думаю, что проблема на уровне подключения файла к С.

требует ‘mkmf’

$ CPPFLAGS << ‘-D_GNU_SOURCE = 1’

have_func (‘splice’,% w (fcntl.h)) или прервать ‘splice (2) не определено’

have_func (‘tee’,% w (fcntl.h)) или прервать ‘tee (2) не определено’

have_func (‘pipe2’,% w (fcntl.h unistd.h))

have_func ( ‘rb_thread_blocking_region’)

have_func ( ‘rb_thread_call_without_gvl’)

have_macro ( ‘F_GETPIPE_SZ’,% вес (fcntl.h))

have_macro (‘F_SETPIPE_SZ’,% w (fcntl.h))

create_makefile ( ‘io_splice_ext’)

gem install io_splice
