ターミナルからのperlモジュールのインストールに失敗する

#前提・実現したいこと
KH Coderをmacにインストールしようとしており、Perlの追加モジュールを入れていたところこけまくった挙句解決できませんでした。
インストール方法については以下のサイトを参考にしております。
KH CoderをMacにインストール
Perlに触るのも初めてですが、なんせ知識の乏しいmake周りでこけているようでご教授いただきたいです。

#発生している問題
KH Corderを起動しようとすると以下のように表示されるため該当モジュールの追加を試みました

bash
$ perl kh_coder.pl

DBD/mysqlが足りないのでcpanによるインストールを試みた結果が以下の通りです。

Perl

PLEASE NOTE:

For 'make test' to run properly, you must ensure that the
database user 'root' can connect to your MySQL server
and has the proper privileges that these tests require such
as 'drop table', 'create table', 'drop procedure', 'create procedure'
as well as others.

mysql> grant all privileges on test.* to 'root'@'localhost' identified by 's3kr1t';

You can also optionally set the user to run 'make test' with:

perl Makefile.PL --testuser=username

I will use the following settings for compiling and testing:

  cflags        (mysql_config) = -I/usr/local/Cellar/mysql/5.7.21/include/mysql
  embedded      (mysql_config) = 
  ldflags       (guessed     ) = 
  libs          (mysql_config) = -L/usr/local/Cellar/mysql/5.7.21/lib -lmysqlclient -lssl -lcrypto
  mysql_config  (guessed     ) = mysql_config
  nocatchstderr (default     ) = 0
  nofoundrows   (default     ) = 0
  nossl         (default     ) = 0
  testdb        (default     ) = test
  testhost      (default     ) = 
  testpassword  (default     ) = 
  testport      (default     ) = 
  testsocket    (default     ) = 
  testuser      (guessed     ) = root

To change these settings, see 'perl Makefile.PL --help' and
'perldoc DBD::mysql::INSTALL'.

まず./configureが実行できず、makeも失敗しました。

続いて、以下を参考にcpanmを用いてインストールを試みました。
