newbie trying to install apr and apr-util for Apache, need help

I downloaded Apache and tried to install but it said I needed apr.

downloaded apr and apr-util

from looking at this instruction, I don't know how to load apr and apr-util to the prescribed subdirectory,/httpd_source_tree_root/srclib/ :

APR and APR-Util
Make sure you have APR and APR-Util already installed on your system. If you don't, or prefer to not use the system-provided versions, download the latest versions of both APR and APR-Util from Apache APR, unpack them into /httpd_source_tree_root/srclib/apr and /httpd_source_tree_root/srclib/apr-util (be sure the directory names do not have version numbers; for example, the APR distribution must be under /httpd_source_tree_root/srclib/apr/) and use ./configure's --with-included-apr option. On some platforms, you may have to install the corresponding -dev packages to allow httpd to build against your installed copy of APR and APR-Util.

I tried ./configure prefix=/httpd_source_tree_root/srclib/, but it didn't like that. I did create all that directory structure by hand, as nothing else seemed to be creating it.

I then tried ruing
./configure
make
make install

Seems to have created another structure of stuff under "local", but nothing working, and I seem to have closed the terminal window that gave me some error messages.

So, sorry to my rambling and lack of pertinent details. How can I fix this, or backtrack and try another route?
