It's not vital, but it is annoying.  Is it that awkward?  Why not load
all found perls into an array, then (warning, inefficient code follows,
but shouldn't be a problem for most systems):

for ($i = 0 ; $i <= $#perlbinaries ; $i++) {
    # replace any instances that are symlinks with their targets
    # and keep doing it until it's not a symlink anymore, or
    # the target doesn't exist
    while ((-e $perlbinaries[$i]) && (-l $perlbinaries[$i])) {
      $perlbinaries[$i] = readlink($perlbinaries[$i]);
       }
    }

# insure that duplicates will be consecutive
@perlbinaries = sort (@perlbinaries);

# too bad there isn't a uniq() like there is a grep() and sort()
for ($i = 0 ; $i <= $#perlbinaires ; $i++) {
       # iteratively remove duplicates
       while ($perlbinaries[$i] eq $perlbinaries[($i + 1)]) {
          splice(@perlbinaries, ($i + 1), 1);
          }
       }

if ($#perlbinaries > 0) {
    # complain about multiple perl binaries
    }
# otherwise, keep running, using $perlbinaries[0] as your perl engine

What's the difference between install.sh and install.tar-fns.sh?  I ran
the former when I installed ...

No problem, I just wanted to be sure that it is known and/or harmless.

Probably.  Hopefully it wont actually cause problems.
