OK, so I got to dig a little further... The problem appears to be the
"unless isabsolute($dir)".

First, instrument with print's (my apologies; I no almost no PERL):

    sub cleandir {
        my $base = shift;
        print "base directory: ", "$base", "\n";

        my $dir = shift;
        print "dir directory: ", "$dir", "\n";

        my $relativeto = shift || ".";

        my $this_catdir = catdir($base,$dir);
        print "this_catdir: ", "$this_catdir", "\n";

        my $is_absolute = isabsolute($dir);
        print "is_absolute: ", "$is_absolute", "\n";

        $dir = catdir($base,$dir) unless isabsolute($dir);
        print "catdir directory: ", "$dir", "\n";

        # Make sure the directories we're building in exists
        mkpath($dir);

        my $res = abs2rel(absolutedir($dir), rel2abs($relativeto));
        #print STDERR "DEBUG[cleandir]: $dir , $base => $res\n";
        return $res;
    }

It produces:

    base directory: /home/jwalton/Desktop/openssl
    dir directory: /include
    this_catdir: /home/jwalton/Desktop/openssl/include
    is_absolute: 1
    catdir directory: /include

It seems like I should be able to drop the "unless isabsolute($dir)",
but it causes problems in later invocations when using "../". Maybe it
needs some like "not isrelative($dir)", too.

Would you like access to the VM? You should be able to jump to it from
the PowerMac to 172.16.4.16 .
