Apache下整合的SVN，由於自己需要加modules,就重新./configure，make make install後啟動apache出現如下錯誤:
httpd: Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_dav_svn.so into server: /usr/local/apache2/modules/mod_dav_svn.so: undefined symbol: dav_register_provider
解決辦法：
重新./configure 增加參數
1./configure -prefix=/usr/local/apache2 -enable-dav -enable-so -enable-maintainer-mode -enable-rewrite
