try executing the following from the command line:
prompt>perl -e 'use Benchmark;'
If your module isn't installed it'll give you an error "Can't locate Benchmark.pm in @INC (@INC contains blah/blah/blah)
Begin failed -- Compilation aborted at -e line 1.
Just a stupid trick executing code to see if a module is installed and if your perl interpreter knows how to find it. The special array @INC contains the pathway in which perl will search to find whatever modules you use and require. You could modify it at compile time with use lib '/path/blah/blah';

Sorry to all, I already had it. I assumed not, and tried to install it with MCPAN.... sorry to all and please don't be too harsh on me
Thanks a lot.

It's a standard module - your distribution should already have it.rdfield | [reply] |
To verify that you've got it, as with most(all?) standard Perl modules, provided you know the name of the module, you should be able to view the perldocs for that module - if the perldocs are present, then the module is present. At a command prompt, do
perldoc Benchmark
If the perldoc for "Benchmark" appears, then you've got it - and the perldocs tell you how to use it.
I'm also including a script that I wrote - I call it "pwhich", which on a *nix platform does the same thing as the "which" command - it tells you where in your search path a command exists. So, pwhich tells you where in your Perl search path(@INC) that the module appears, *AND* it tells you what version of the module is installed there - according to the $VERSION string found in the module:

#!/usr/bin/perl -w

# Name: pwhich

# Takes In: 1. Perl module name (Ex: DBI, DBD::Oracle)

# where "XYZ" is the name of a Perl module speci

# Or b. line 1 - the @INC location of the perl module,

Thank you for the script ;-)

Benchmark is all perl, so just go ahead and download the perl5.8 version (although you should already have it).

For a complete list of modules that come with the perl distribution, you can look at perlmodlib or on your system
type perldoc perlmodlib

Yup.
