Arvados

I installed go in the following dir
go version 1.5
/root/go
workspace = /root/work
GOPATH=/root/work
GOROOT=/root/go
PATH+ added /root/go/bin

Arvados dir = /root/arvados

Please help what do I need to do to get this fixed.
Ran the command ./build.sh in the director /root/arvados/docker
After some time it throw the following error

ln -sfn ../../../../.. keep/generated/src/git.curoverse.com/arvados.git
GOPATH=/root/arvados/docker/keep/generated go get git.curoverse.com/arvados.git/services/keepproxy

1. git.curoverse.com/arvados.git/sdk/go/arvadosclient
   keep/generated/src/git.curoverse.com/arvados.git/sdk/go/arvadosclient/pool.go:13:2: error: reference to undefined identifier ‘sync.Pool’
   sync.Pool

The sync.a fils is there in the right folder and I had installed go1.5.
