Sunucuma mysql 5.5 kurmak istiyorum ama bu hatayla karşılaşıyorum nasıl çözebilirim?

===> mysql55-client-5.5.44_1 pkg(8) must be version 1.3.8 or greater, but you have 1.2.4_1. You must upgrade the ports-mgmt/pkg port first.
*** Error code 1

Stop.
make: stopped in /usr/ports/databases/mysql55-client
