Installation Library Problems With Soalris 8

Hello, I am attempting to install PHP4 on Sparc Solaris 8. After running the installs, I get this message on startup. A colleague of mine does not get thin on Linux. Any ideas? /etc/init.d/httpd start starting apache httpd daemon /usr/local/apache/bin/apachectl graceful: httpd not running, trying to start Syntax error on line 791 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: ld.so.1: /usr/local/apache/bin/httpd: fatal: /usr/local/apache/libexec/libphp4.so: unknown file type /usr/local/apache/bin/apachectl graceful: httpd could not be start Thanks in advance.
