pthread_create not found, on "make" of OSRM-Project

Question

I am trying to set up OSRM-project on my linux server, however am experiencing issues while doing so. I have the latest versions of the dependencies, and have also installed and setup pthreads: pecl pthread install

then adding it to php, and recompiling php.

Below is the information:

Centos 6 64bit, trying to set up OSRM-Project.

downloading soure, then:

cd osrm-backend
mkdir -p build
cd build
cmake -D STXXL_LIBRARY=/usr/local/include/stxxl.h ..
make

Build fails on make:
