lamp设置问题

我在linux安装了apache2.0后,80端口的关闭与启动一切正常,然后我又安装了php.4.4,这些过程中都没提示什么错误,我再次重启apache,提示
Syntax error on line 232 of /usr/local/apache2/conf/httpd.conf:
Cannot load /usr/local/apache2/modules/libphp4.so into server: /usr/local/apache2/modules/libphp4.so: cannot restore segment prot after reloc: Permission denied
我查看下httpd.conf文件的第232行,是LoadModule php4_module        modules/libphp4.so
请问大虾们是什么原因啊

php的编译步骤:
./configure --with-mysql --with-apxs2=/usr/local/apache2/bin/apxs
make
make install
cp php.ini-dist /usr/local/lib/php.ini
