There's no doubt some more sophisticated way of doing this, but I'd probably just try to require each package in turn in a string eval. This should give you the idea:
#!/usr/bin/perl
use strict;
use warnings;
my @packages = qw/
Net::IP
Net::CIDR
List::BinarySearch
/;
for my $package (@packages) {
eval "require $package";
if ($@) {
print "Couldn't find package '$package'\n";
}
else {
print "Found package '$package'\n";
}
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
