First, install Go, set your GOPATH, and make sure $GOPATH/bin is on your PATH.
brew install go export GOPATH="$HOME/go" export PATH="$PATH:$GOPATH/bin"
Next, fetch and build the two binaries.
go get github.com/fogleman/pack3d/cmd/pack3d go get github.com/fogleman/pack3d/cmd/binpack
Note that pack3d runs until stopped, writing its output to disk whenever a new best is found.
