Solution:
in boost/config/suffix.hpp
26:#ifndef BOOST_CONFIG_SUFFIX_HPP
27:#define BOOST_CONFIG_SUFFIX_HPP

change to 
25:#include <unistd.h>
26:#ifndef BOOST_CONFIG_SUFFIX_HPP
27:#define BOOST_CONFIG_SUFFIX_HPP

250:    || defined(_PTHREADS) || defined(__APPLE__) || defined(__DragonFly__)) \

change to 
250:    || defined(_PTHREADS) || defined(__APPLE__) || defined(__DragonFly__) || (defined(_POSIX_THREADS) && (_POSIX_THREADS+0 >= 0))) \
