Any one have experience creating a spec file for a golang project?

I am trying to follow https://fedoraproject.org/wiki/PackagingDrafts/Go but with no success.

Here is my compile line 

%gobuild -ldflags -X main.AppVersion=%{Version} -o bin/go-md2man %{buildroot} go/cmd/orchestrator/main.go

And here is my error

+ GOPATH=/home/boneal/rpmbuild/BUILD/orchestrator-1.4.550:/usr/share/gocode

++ go version

+ echo 'Building via go version go1.4.2 linux/amd64'

Building via go version go1.4.2 linux/amd64

+ %gobuild -ldflags -X 'main.AppVersion=%{Version}' -o /home/boneal/rpmbuild/BUILDROOT/orchestrator-1.4.550-1.x86_64 go/cmd/orchestrator/main.go

/var/tmp/rpm-tmp.Atohvw: line 40: fg: no job control

error: Bad exit status from /var/tmp/rpm-tmp.Atohvw (%build)

I have tried using -o go-m2dman and -o /usr/bin/go-md2man they result in the same error. Same with removing the ldflags and the version.
