panic% cd /home/stas/src/httpd_perl/mod_perl-1.xx

panic% perl Makefile.PL \
    APACHE_SRC=../apache_1.3.x/src \
    DO_HTTPD=1 USE_APACI=1 EVERYTHING=1 \
    APACHE_PREFIX=/home/httpd/httpd_perl \
    APACI_ARGS='--prefix=/home/httpd/httpd_perl'

If you need to pass any other configuration options to Apache's ./configure, add them after the —prefix option. For example:

APACI_ARGS='--prefix=/home/httpd/httpd_perl \
            --enable-module=status'

Notice that just like in the httpd_docs configuration, you can use —target=httpd_perl. Note that this option has to be the very last argument in APACI_ARGS; otherwise make test tries to run httpd_perl, which fails.

Now build, test, and install httpd_perl.

panic% make && make test
panic# make install

Upon installation, Apache puts a stripped version of httpd at /home/httpd/httpd_perl/bin/httpd. The original version, which includes debugging symbols (if you need to run a debugger on this executable), is located at /home/stas/src/httpd_perl/apache_1.3.x/src/httpd.

Now rename httpd to httpd_perl:

panic% mv /home/httpd/httpd_perl/bin/httpd \
    /home/httpd/httpd_perl/bin/httpd_perl

and update the apachectl utility to drive the renamed httpd:

panic% perl -p -i -e 's|bin/httpd|bin/httpd_perl|' \
    /home/httpd/httpd_perl/bin/apachectl
