Docker image sleeve/pulsar does not exist

[simphax]

I'm not entirely sure if I'm doing this right, but when running make build it seems like sleeve/pulsar is not available in the public docker repository. Am I supposed to create this image some other way? A build guide would be awesome. I would like to try another algorithm for QualityFactor

I had to do several steps to make it build from and for Mac OS X.

1. Install Docker & Golang
2. git fetch and cd into the pulsar repo
3. export GOPATH=/any/path
4. go get
5. Edit $GOPATH/src/github.com/steeve/libtorrent-go/libtorrent.swigcxx according to gen2brain/libtorrent-go@66b849f
6. Edit Dockerfile and add ENV PKG_CONFIG_PATH /usr/x86_64-apple-darwin14/lib/pkgconfig before the RUN command
7. make build-envs
8. make build TARGET_OS=darwin TARGET_ARCH=x64 MARGS="list"

I'm sure that there is a more streamlined way to build. Please enlighten me.
