How can I find out where a Perl module is installed?

Question

How do get the path of a installed Perl module by name, e.g. Time::HiRes?

I want this just because I have to run my perl script on different nodes of a SGE

Answer 1

It seems like the simplest way is perldoc -l Time::HiRes.

If that isn't available for some reason, here's a pragmatic solution:

Step 1: Instantiate the module in your script...

#! /usr/bin/perl -w
use Time::HiRes();
new Time::HiRes();

Step 2: Execute the script with the Perl graphical debugger...

export PERL5LIB=$PERL5LIB:~/perl ## tell perl where to look for "Devel"/"ptkdb.pm"
perl -d:ptkdb (yourscript.pl)

Step 3: Step in to the new call.

The full pathname of the module will be displayed on the title-bar of the debugger window.

Another approach that might be useful would be to search all of the folders in $PERL5LIB.
