距mysql+php+apache成功只有一步之遥

请教各位大哥们：
mysql 已能正常工作，php、apache已按要求安装完成。
/usr/local/apache/conf/httpd.conf中需要添加更改的地方
也已做好。但/usr/local/apache/bin/apachectl start时，
提示：
syntax error on line 205 of /user/local/apache/conf/httpd.conf:
canot load /usr/local/apache/libexec/mod_vhost_alias.so into
server:ld.so.1:  /usr/local/apache/bin/httpd:fatal:relocation error:
file /usr/local/apache/libexec/mod_vhost_alias.so:symbol
ap_os_is_path_absolute:referenced symbol not found.
/usr/local/apache/bin/apachectl start:httpd could not be started.

不知道是那还没设置好？???还是apache或php编译过程有问题????
