提示如下： 
Apache::StatINC: Can't locate /usr/local/Chart-2.2/blib/lib/Chart/Lines.pm 
Apache::StatINC: process 23820 reloading Sagem/Bugs.pm. 
Apache::StatINC: Can't locate /usr/local/Chart-2.2/blib/lib/Chart/Base.pm 
Apache::StatINC: process 23820 reloading Sagem/AuthCookie.pm. 
[Wed May 12 09:19:30 2010] [error] Undefined subroutine &Sagem::AuthCookie->login_form::handler called. 

/usr/local/Chart-2.2/blib/lib/Chart/Lines.pm这些文件都是存在的。 
login_form这个函数应该没有问题。
