I compiled and successfully executed the binary on my mac and then copied it to the ubuntu machine whose go env is show above. When I call myprog binary, I get
bash: /usr/local/go/bin/myprog: cannot execute binary file: Exec format error
I had the same problem. I installed 64-bit version of go instead of 32-bit version. After installation of 32-bit version it works fine.
Since go 1.5, cross compiler has gotten pretty easy. Something like
env GOOS=linux GOARCH=amd64 go build -v github.com/constabulary/gb/cmd/gb
