What about pushing them onto an array and then joining it. Join already has this logic for needing the | or not, and then you could put pages in the middle easily.

  my @links = ();
  push @links, $firstlink if $. != 1;
# push @links, pagelink($page) foreach my $page (@pages);
  push @links, $lastlink if $. != $total_number_of_lines;
  print join("|",@links);

Easy to ready and you can have some added functions (maybe, dunno how your code works.) (:
