	to create a module there, run:
	go mod init
Command failed:  cd "/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_devel_govendor/govendor/work/govendor-1.0.9" && go install 
Exit code: 1

No ports depend on it.

The govendor repository was archived in 2020 and its README says:

Please don't use this tool anymore.

Please use Go modules.

Can this port be deleted?
