我一直试图安装Crypt::PBC几周但未能这样做。我首先使用了cpan install Crypt::PBC，这就是结果：

然后当我说是的时候，我意识到voltar.org链接已被破坏。这是生成的消息：

所以我解压缩了使用Crypt-PBC-0.9000.tar.gz下载的tar -xvzf Crypt-PBC-0.9000.tar.gz。内容已成功解压缩。之后，因为其中有Makefile.PL，我使用了perl Makefile.pl。在makefile中，我将Web请求更改为http://crypto.stanford.edu/pbc/files作为pbc文件的源，然后再次使用perl Makefile.pl。生成以下内容：
Use of qw(...) as parentheses is deprecated at inc/Devel/CheckLib.pm line 164.

(You do need libgmp installed in order for this PBC.so to function...)

我尝试在incpath和libpath中包含各种GMP文件，但没有任何帮助。您能否告诉我这个makefile需要哪些特定的GMP文件，以便我可以在INC路径中包含这些文件？
