Installation with mod_perl / mod_so

I'm having difficulty installing PHP (surprise) alongside mod_perl and mod_so. I've got the source tarballs for PHP (4.0.6), mod_perl (1.26), and apache (1.3.20), and unpacked them in my home directory. Then I've done: $ vi apache_1.3.20/src/Configuration # uncommented the mod_so include line $ apache_1.3.20/configure # to get the default makefiles $ cd mod_perl-1.26 $ make # make install $ cd ../php-4.0.6 $ make # make install $ cd ../apache_1.3.20 $ LIBS=perl -MExtUtils::Embed -e ldopts $ CFLAGS=perl -MExtUtils::Embed -e ccopts $ export LIBS CFLAGS $ ./configure \ --activate-module=src/modules/perl/libperl.a \ --activate-module=src/modules/php4/libphp4.a \ --enable-module=rewrite \ --enable-module=status \ --enable-module=expires \ --enable-module=perl $ make # make install # cd ../php-4.0.6 # cp php.ini-dist /usr/local/lib/php.ini # /usr/local/apache/bin/apachectl start This all seems to work with no error messages, and when I start the web server, I get: [Tue Aug 14 16:19:19 2001] [notice] Apache/1.3.20 (Unix) PHP/4.0.6 mod_perl/1.26 configured -- resuming normal operations in my installed apache error log. Also: $ /usr/local/apache/bin/httpd -l shows me that mod_perl.c and mod_php4.c (but not mod_so.c) are compiled in. However, when I try to load a PHP page which worked fine before the 'upgrade', I get the error: "Fatal error: Failed opening required 'class.DBI' (include_path='.:/usr/local/lib/php') in /usr/local/apache/htdocs/irm/include/irm.inc on line 77" There is a class.DBI file in /usr/local/apache/htdocs/irm/include/DBI but it doesn't look like it's finding this. Is there something wrong with my PHP installation? Also, how do I get it to recognise mod_so?
