I noticed that apr installed without --prefix option installs apr to /usr/local by default.
I also noticed apr-utils requires "--with-apr=/usr/local/apr" option to configure.
And another thing is apache2.4 installed with "
--prefix=/usr" option will install inside /usr path, merging things with already existing folders and creating folders which doesn't exist.
And the installation which is only made this way is working fine and I can see result in 127.0.0.1.
