php install probs

I get this error message when trying to start apache up for the first time with php4. Config is: apache 1.3.14 php4.0.3pl3 Red Hat 6.0 None of these packages are RPM's, I compiled it all from source, including the apache mod_so support. I didn't get any errors or warnings during configure or compile. Below are the two relevant lines from my httpd.conf files: LoadModule php4_module libexec/libphp4.so AddType application/x-httpd-php .php Now this is the confusing part. The php INSTALL file says I only need that second line, but if I only use that second line then my test.php script comes up as source rather than displaying it's intended output. [root@www conf]# apachectl restart /usr/local/apache/bin/apachectl restart: httpd not running, trying to start Syntax error on line 207 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: zendtext /usr/local/apache/bin/apachectl restart: httpd could not be started [root@www conf]# Anyway, help would be mucho appreciated. Thanks folks! -todd
