Man, what an ordeal this was! I kept getting linking errors. Here's my procedure. You'll find similar procedures in the mod_perl and mod_ssl docs, but for some reason without the exact right switches I was getting bogged down with little errors.

First, make some junk directory and plop the mod_ssl, mod_perl and apache tarballs into it; untar them there.

cd mod_ssl-2.8.10-1.3.26

./configure --with-apache=../apache_1.3.26 --with-ssl=../openssl-0.9.6g --prefix=/usr/local/apache

cd ../mod_perl-1.27

perl Makefile.PL 
  EVERYTHING=1 \\

  USE_APACI=1 \\

  PREP_HTTPD=1 \\

  DO_HTTPD=1 \\

  APACHE_SRC=../apache_1.3.26 \\

  SSL_BASE=/usr/local/openssl/ \\

  APACHE_PREIX=/usr/local/apache

cd ../mod_ssl-2.8.10-1.3.26

./configure \\

  --with-apache=../apache_1.3.26 \\

  --with-ssl=../openssl-0.9.6g \\

  --prefix=/usr/local/apache\\

  --activate-module=src/modules/perl/libperl.a \\

  --enable-module=perl

cd ../apache_1.3.26

make
make certificate TYPE=test
make install
