LoadModule php4_module        libexec/libphp4.so

When the previous line is present in the httpd.conf file, Apache will not load when the "./apachectl restart" command is executed. I get the error:

[root@ip234-164 bin]# ./apachectl restart
./apachectl restart: configuration broken, ignoring restart
./apachectl restart: (run 'apachectl configtest' for details)

I then run:

[root@ip234-164 bin]# ./apachectl configtest
Syntax error on line 207 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/libphp4.so into server: undefined symbol: uncompress

PHP was configured as follows:
./configure --with-mysql=/usr/local/mysql --with-apxs=/usr/local/apache/bin/apxs --prefix=/usr/local/php --with-track-vars --with-trans-id
