Quick and dirty (Windows 7, Perl 5.8.9):
Module check_module.pm:
package check_module;
use Exporter;
our @ISA = qw(Exporter);
our @EXPORT = qw(@checks);
our @checks = (
{
name => 'Anybody home?',
script => 'qq/echo $home_dir/',
},
);
1;
Note esp. that 'qq/echo $home_dir/' is single-quoted in the .pm file.
Script:
c:\@Work\Perl\monks\ExReg>perl -wMstrict -le
"use strict;
use warnings;
use check_module;
my $home_dir = '/home/mine/';
for my $check ( @checks ) {
print qq{Checking $check->{name}};
my $evaled_script = eval qq{$check->{script}};
print `$evaled_script`;
}
"
Checking Anybody home?
/home/mine/
(Update: The trick here is to eval the $check->{script} string from the module in the scope of the script in which $home_dir is declared and initialized.)
Update 1: If you had included the use warnings; use strict; statements in the .pm module (after the package statement), you would have had a slightly earlier and possibly slightly more informative notification that something was going sideways.
Update 2:
... [a] system that cannot use CPAN ...
See Yes, even you can use CPAN.

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).
