go-md2man is missing

Trying to build the tools this command is missing. I haven't found any information on getting this for oraclelinux. Can you provide that information?
When other dependencies can I expect preventing me from a successful build?
Thanks in advance.

go get -u github.com/cpuguy83/go-md2man, but you don't need it unless you want to build the man pages.

Anyway I can override the go version?
