$ podpath Cwd
/usr/local/devperl/lib/5.00554/Cwd.pm
It works with alternate installations, too:
$ devperl -S podpath perlfunc
/usr/local/devperl/lib/5.00554/pod/perlfunc.pod
$ oldperl -S podpath IO::Handle
/usr/lib/perl5/i386-linux/5.00404/IO/Handle.pm
$ filsperl -S podpath Thread
/usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread.pm
