Compile PHP with Pthreads enabled on Ubuntu

I cannot make Pthreads work on a Ubuntu machine and i need somebody to do it for me. I will create an empty (or a LAMP) stack Ubuntu 14.04 x64 on Digital Ocean and give root password to you. You will compile PHP with Pthreads enabled, that's it. Please write ZTS-enabled at the begining of your proposal. If you know what you are doing it's a 10-20 minutes job. Thank you.
