unable to build on FreeBSD

Reproduce the failure on a FreeBSD 13.0-RELEASE system using the package setup and gmake command shown. Start with Makefile:11 and the reported build errors in the Go dependencies, then verify that gmake completes and produces bin/flyctl on FreeBSD.

Describe the bug

I'd like to get flyctl into FreeBSD ports tree. The first step is to compile from source, which fails:

### boot a FreeBSD 13.0-RELEASE image somewhere and get root
$ sudo -s
### install latest go and git tools from packages
# sed -i '' -e 's/quarterly/latest/' /etc/pkg/FreeBSD.conf
# pkg install -y lang/go devel/gmake git-tiny
# exit
### switch back to non-root
$ git clone https://github.com/superfly/flyctl
$ cd flyctl && gmake

% gmake build

not familiar enough with go to know if this is fixable or not.
