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. *Can some one explain why I cannot start server from */usr/local/apache2 ? Please help me.
