我正在尝试安装GD模块（v2.56）。我可以使用'perl Makefile.PL'成功创建make文件然后'make'但是当我运行'make test'时我得到以下错误： -
t/Polyline.t .. Can't locate loadable object for module GD in @INC (@INC contains: /root/.cpan/build/GD-2.56/blib/lib /root/.cpan/build/GD-2.56/blib/arch /usr/local/lib/perl5/site_perl/5.22.0/x86_64-linux /usr/local/lib/perl5/site_perl/5.22.0 /usr/local/lib/perl5/5.22.0/x86_64-linux /usr/local/lib/perl5/5.22.0 .) at /root/.cpan/build/GD-2.56/blib/lib/GD/Polyline.pm line 45.

我已经检查并确认GD.pm（2014年10月28日）是在Perl INC路径中，我已经安装了gd，gd-devel，gdbm和gdbm-devel
服务器是Centos 6，perl是v 5.22.0，gd是v2.0.35。
