I've successfully compiled without errors and installed php with mysql, ftp, trackvars and imap support.. when I for PHP 4: ./configure --activate-module=src/modules/php4/libphp4.a, it doesn't seems to work and this error is given to me... Normally, without --activate module... all is working.... Why?

[root@cosmosis apache_1.3.19]# ./configure --activate-module=src/modules/php4/libphp4.a
