The only mandatory requirement for the Phoronix Test Suite on Linux, Solaris, *BSD, Hurd, and Mac OS X operating systems is PHP CLI (packages for it are generally called php5-cli or php-cli or just php). Only PHP 5.3 or greater is needed and not a web server or other packages commonly associated with PHP. As an alternative to PHP, the Facebook HHVM (HipHop Virtual Machine) interpreter is also supported for running the Phoronix Test Suite.
Many of the benchmarking profiles do require the standard development tools/libraries (GCC compiler, etc) and other common programs. However, on many Linux distributions and operating systems the Phoronix Test Suite is able to use the software's package management system for installing these additional dependencies.
Phoronix Test Suite 6.4 is currently under development. The official release of Phoronix Test Suite 6.4 will be made available in Q2'2016.
The open-source Phoronix Test Suite and Phoromatic benchmarking software is developed on GitHub where you can track the latest development code.
