[Freeswitch-dev] Libraries (http://files.freeswitch.org/ or system)

Hello everyone, I have tried to find this answer, but have been unable to do so. Fedora has most of the libraries and programs used by freeswitch. Can I use the system ones or do I need to use the ones at files.freeswitch.org? I understand they are needed on windows for compilation reasons, but I am interested in Linux.
