Se não houver um pacote, você pode compilar seu próprio php
1. Download php, extract it and cd into the directory
2. ./configure - add options you need and do not forget --with-apxs2. It will compile the module for apache. (You can check the currunt options used to compile php in phpinfo()). You can see the help and options with ./configure --help
3. make - this will compile the php
4. make install - this will install the php
