You might consider adding to the instructions that people need the EPEL repo enabled

pretty sure you also need openssl-devel.

In any case, it didn't get past ./configure --enable-ssl --enable-so --enable-http2 --with-mpm=event --with-included-apr --with-ssl=/usr/bin --prefix=/usr/local/apache2 until I installed it.
