libphp4.so: undefined symbol: pam_start

Linux Apache 1.3.19 PHP 4.1.2 INSTALLED as a server module (by me, with no problems) Trying to install version 4.2.1, I finally got the configuration right: ./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --enable-sysvsem --enable-track-vars --with-jpeg-dir=/usr/local/bin --with-imap --with-imap-ssl=/usr/local/ssl --enable-trans-sid --with-xml 'make' worked ok, and 'make install' too. I stopped apache, and then: # /usr/local/apache/bin/apachectl start Syntax error on line 236 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: pam_start /usr/local/apache/bin/apachectl start: httpd could not be started I thought tihs was something that version 4.2.1 used, so I decided to cancel my php update until I found out more about this. Thus, I decided to re-install version 4.1.2... And got the same result: # /usr/local/apache/bin/apachectl start Syntax error on line 236 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: pam_start /usr/local/apache/bin/apachectl start: httpd could not be started I checked out PAM a bit, and found it too daunting, but what I really want to know is, how come I could install php 4.1.2 with no problems whatsoever and then have this problem while re-installing it? This is a server I'm talking about, and now its web server is down. I know, I could comment the lines that load the php module, but I /need/ php. Please help. I have no idea what has happened to my box, and I don't want to kill it by installing PAM incorrectly (if indeed that would fix anything).
