If your goal is just to build and install Apache with mod_perl out of their source trees, and you have no interest in further adjusting or enhancing Apache, proceed as we described in Chapter 2:

panic% tar xzvf apache_1.3.xx.tar.gz
panic% tar xzvf mod_perl-1.xx.tar.gz
panic% cd mod_perl-1.xx
panic% perl Makefile.PL APACHE_SRC=../apache_1.3.xx/src \
panic% make && make test
panic# make install
panic# cd ../apache_1.3.xx
panic# make install

This builds Apache statically with mod_perl, installs Apache under the default /usr/local/apache tree, and installs mod_perl into the site_perl hierarchy of your existing Perl installation.
