so what, on a modern linux you can tweak much more
you wold ever be able on a Mac AND it is much
faster without tuning for mysql, php, apache....

on a clean operating system there is NO DIFFERENCE between OS and software

your argumentation is the one of a apple-user which never did understand
the benfits of a centralized package managment because you do not know it

* consistency
  * programs and libraries are matching
  * clean dependencies

* security
  * each library only ONCE, patches are fixing EVERY application using this lib
  * permissions - a typical RPM makes sure the permissions of each file
  * never give the user write permissions to the applications folder

especially the points of security are badly missing on MacOSX which
is these days the most insecure recent OS out there

you need different mysql-services with different config on one machine
well, write yor my.cnf whereever you want and create an additional service

you need more webservers with different module/php-configurations?
well, do the same with httpd.service

you need different versions of a sfotware?
well, learn to use rpmbuild and RTFM ./configure
