extman登陆页面不能显示验证码图片(安装perl_GD模块)
extman的首页能进了，登陆框中的验证码图片又不能显示了，/var/log/httpd-error.log中的错误信息：
[Wed Sep 12 14:20:40 2007] [error] [client 218.104.52.212] Can’t locate GD.pm in @INC (@INC contains: /usr/local/www/extman/libs /usr/local/lib/perl5/5.8.8/BSDPAN

extman的bbs上也有人提出了此问题，原因是perl的GD模块没有正确安装，此GD模块不是PHPINFO中的GD模块，而是Perl上的GD模块，安装如下：
mail# cd /usr/ports/graphics/p5-GD
mail# make install
mail# reboot
重启后，再次登陆，验证图片就显示了，问题解决。
