Thanks for the info. Isn't this what the Perl Package Manager is for?

I'm trying to implement the following code:

print $response->content; # or whatever
}
else {

######################################################
The code works but what I don't get is how do I know if LWP::UserAgent
(or even LWP) is installed on my machine.
If I use the Perl Package Manager and type: query LWP
I get the following:
Querying target 1 (ActivePerl 5.8.7.815)
1. LWP-UserAgent-Determined [1.03] a virtual browser that retries
errors
This is a module (?) I installed myself.
Is LWP::UserAgent installed--I guess it must be because the code works.
Can someone explain this?
First of all it should be
use LWP;
which does the 'require LWP::UserAgent' for you as well as checking that
you're
running on an adequate version of Perl and setting the LWP version number.
And you can find out whether LWP is installed by entering
perl -MLWP -e"1"
on the command line. It will shout if the module isn't there. Your
program will
also die at the require if it doesn't find LWP::UserAgent, saying
something like
'Can't locate LWP/UserAgent.pm in @INC'.
HTH,
Rob
