编译Apache遇到的一个问题

今天在一台服务器上配置Django环境 ，打算用Apache httpd + mod_python + Django。原来的Apache用的是work MPM，按照Django的文档，mod_python最好和prefork MPM配合，于是打算重新编译一下Apache。编译的时候发现以下的错误

exports.c:1002: error: previous definition of 'ap_hack_apr_gid_name_get' was here

折腾了好一会儿，感觉可能是前阵子手工装了apr-util和apr的rpm包，可能是导致某些冲突了。于是在执行configure时加上 --with-included-apr，再make，就OK了。
