Conditional use of Win32::TieRegistry

[hilitai]

I have a script that is used on Windows and Linux machines. Now, I need to have the script make a registry change on windows. Using Win32::TieRegistry seems reasonable, however I can't figure out a way to have this module work on Windows, and at the same time not get @INC errors on Linux.

My problem, I think, is that Win32::TieRegistry module appears to create a globally-scoped Registry object when the interpreter hits the 'use ...' statement. This object is used in all further interaction with the registry. If I try to put the 'use Win32::TieRegistry' into an 'eval {}', as I do when trying to load modules that may not exist, I get "Global symbol $Registry requires explicit package name..." errors.

Below is a simple script that encapsulates my problem. Two lines are commented out; if either one is uncommented, the script will work on either Windows *or* Linux; but if both are either left alone or uncommented, it fails on both platforms:

#!/usr/bin/perl

use strict;
my $usemod = 0;
eval { require Win32::TieRegistry; }; 

if ($@) {
   warn "No module\n";
}
else {
   $usemod = 1;
}
if ($usemod) {
#  my ($Registry, $IEKey);              # If I expose this line, Windo
+ws FAILS ($IEKey remains null); comment out, Windows WORKS
#  use Win32::TieRegistry(Delimiter=>"/");  # If I expose this line, L
+inux FAILS (@INC compile error); comment out, Linux WORKS
   my $IEKey = $Registry->{'HKEY_CURRENT_USER/Software/Microsoft/Inter
+net Explorer/Main/'};
   print $IEKey, "\n";
}
else {
   print "None of that stuff here\n";
}

Enlightenment sought, thanks in advance.
