I figured it out. GOPATH supports a colon deliminated list of paths to search, but speer ignores this. Instead, speer should be searching this list for the first match.

@cornfeedhobo Thanks for filing the issue and for figuring out the problem. Will put a commit for it(unless you want to put a PR for it 😄).
