Mysql Orchestrator build.sh in Mac OSX shows "cannot use hostnameResolvesLightweightCache.cache.Items()"

I am trying to build Mysql Orchestrator binaries for Mac OSX Yosemite. After executing the build.sh script it shows the error....

Building via go version go1.6.2 darwin/amd64

github.com/outbrain/orchestrator/go/inst ../Cellar/go/1.6.2/libexec/src/github.com/outbrain/orchestrator/go/inst/resolve.go:186: cannot use hostnameResolvesLightweightCache.cache.Items() (type map[string]cache.Item) as type map[string]*cache.Item in return argument

Thanks!
