找不到添加到路径的命令 - sail_align

我正在尝试按照这些说明构建sail_align程序。到目前为止一切顺利，我已经完成了最后的第四步，没有出现错误：

4) sudo ./Build install
This command will install the module. 
The following perl scripts will be added to your path: sail_align, sail_align_parallel

但是，当我运行以下命令来测试安装时：

sail_align -i support/data/timit_5.wav -t support/data/timit_5.txt \ 
-w support/test/local -e timit_sample_test -c config/timit_alignment.cfg

我收到消息说找不到 sail_align 命令。我究竟做错了什么？这是Build文件的脚本：

  $progname = basename($0);
  $orig_dir = Cwd::cwd();
  my $base_dir = '/home/maximus/sail_align-master';
  if (!magic_number_matches()) {
    unless (chdir($base_dir)) {
      die ("Couldn't chdir($base_dir), aborting\n");
    }
    unless (magic_number_matches()) {
      die ("Configuration seems to be out of date, please re-run 'perl Build.PL' again.\n");
    }
  }
  unshift @INC,
    (

    );
}

close(*DATA) unless eof(*DATA); # ensure no open handles to this script

use Module::Build;
Module::Build->VERSION(q{0});

# Some platforms have problems setting $^X in shebang contexts, fix it up here
$^X = Module::Build->find_perl_interpreter;

if (-e 'Build.PL' and not Module::Build->up_to_date('Build.PL', $progname)) {
   warn "Warning: Build.PL has been altered.  You may need to run 'perl Build.PL' again.\n";
}

# This should have just enough arguments to be able to bootstrap the rest.
my $build = Module::Build->resume (
  properties => {
    config_dir => '_build',
    orig_dir => $orig_dir,
  },
);

$build->dispatch;

编辑

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

locate sail_align什么都不输出

运行find / 'sail_align'输出如下
