　　在Fedora/RHEL/CentOS中，perl 的library默认安装路径为：
　　@INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .)
　　如果要使用自定义的perllib，就需要参考以下的设置了。
　　EDIT: Putting the right solution first, originally fromthis question. It's the only one that searches relative to themoduledirectory:

use FindBin;         # locate this script
use lib "$FindBin::Bin/.."; # use the parent directory
use yourlib;

　　There's many other ways that search for libraries relative to thecurrentdirectory. You can invoke perl with the -I argument, passing the directory of the other module:

perl -I.. yourscript.pl

　　You can include a line near the top of your perl script:

use lib '..';

　　You can modify the environment variable PERL5LIB before you run thescript:

export PERL5LIB=$PERL5LIB:..

　　The push(@INC) strategy can also work, but it has to be wrapped in BEGIN{} to make sure that the push is run before the module search:

BEGIN {push @INC, '..'}
use yourlib;
