[Freeswitch-users] Howto install ESL lua, perl, python, ruby mods?

Hi all, None of the Makefiles in src/libs/esl and src/libs/esl/{lua,perl,python,ruby} seem to have instructions how to install those modules. Looking at the respective Makefiles I'm pretty clueless which files to put where. The wiki does not seem to have the answer. Anyone have an idea? Thanks, Patrick
