升级后无法加载（和重新安装）Socket.pm

我刚刚将Slackware64升级到14.1，并且在其中找到了Perl 5.18。Socket.pm现在抱怨它是为另一个Perl版本（5.16）编译的。这是错误：

Perl API version v5.16.0 of Socket does not match v5.18.0 at /usr/share/perl5/XSLoader.pm line 92.

不幸的是，即使使用，我什至无法重新安装Socket.pm cpan。

据我了解，Socket.pm是Perl的核心模块。因此，我认为它会与Perl一起升级。

这是当前位于的目录@INC：

$ perl -E'say for @INC'
/home/francesco-salix/perl5/lib/perl5/x86_64-linux-thread-multi
/home/francesco-salix/perl5/lib/perl5
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5
.

我看到一些文件夹似乎是重复的，但实际上我不知道它们是否应该那样。但是，Socket.pm前两个路径中没有任何内容（我假设cpan在我的用户下运行时添加了该位置，而我Socket.pm同时拥有/usr/local/lib64/perl5/和的文件/usr/lib64/perl5。
