Thank you, GrandFather.

I just came back to report that I finally sorted it out. Only to find your kind words of wisdom. :)

This is what I ended up with (pageblocks.pm): 

use strict;
package webblocks;

1; # LOADING THIS MODULE in index.cgi returns UNDEF || FALSE without t
+his

sub print_xmlheader {
return "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
}

sub print_xmldtd {
return "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"h
+ttp://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">
<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en
+\">
<head>
    <meta http-equiv=\"content-type\" content=\"application/xhtml+xml;
+ charset=utf-8\" />\n";
}

...and in index.cgi: 
print "content-type:text/html; charset=utf-8\n\n";

use lib ('./');
use pageblocks;

print pageblocks::print_xmlheader();
print pageblocks::print_xmldtd();
 ...

I notice the version you posted retains my original print statements. Is there any reason I shouldn't use the return statements I've just chosen?

"Define "actually works"." So noted. Thank you.
