This is a nice trick, but it won't work if the script or or any modules that are loaded do a use lib or unshift @INC
Something like this should work, as long as require is not overriden elsewhere:
package ShowDependencies;
use strict;
*CORE::GLOBAL::require = \&show_require;
sub show_require (;$) {
my $module = shift;
print STDERR $module, $/;
my $retval = eval "CORE::require( $module )";
die $@ if $@;
return $retval;
}
1;
There is also a module (Module::Dependency) on the CPAN that builds a list of dependencies.
update: added use strict

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).

or How to display code and escape characters
are good places to start.
