FreeBSD: mariadb55 конфликтует с mysql55

Я пытаюсь установить percona-toolkit как пакет / порт в моей системе:

[root@alexus ~]# uname -a
FreeBSD alexus.org 9.2-RELEASE-p5 FreeBSD 9.2-RELEASE-p5 #0 r265974: Wed May 14 07:57:04 PDT 2014     root@jj3.myibay.com:/usr/obj/usr/src/sys/R610  amd64

[root@alexus ~]# cd /usr/ports/databases/percona-toolkit/ && make config
===> No options to configure
[root@alexus /usr/ports/databases/percona-toolkit]#

я делаю НЕ хотите удалить и / или заменить существующий mariadb55-client и / или mariadb55-server с участием mysql55-client.

Что я должен делать?

Выглядит как p5-DBD-mysql был "виноват":

[root@alexus /usr/ports/databases/percona-toolkit]# pkg install p5-DBD-mysql

но я все равно смог установить его, используя:

[root@alexus /usr/ports/databases/percona-toolkit]# make -C WITH_MYSQL_VER=55m install
