Unable to figure out dependencies for spray.io's spray-servlet module - scala-2.10

Question

Relevant parts of my build.sbt are here:
libraryDependencies ++= Seq (
"org.scalatest" % "scalatest_2.10" % "1.9.1" % "test",
//Spray dependencies
"io.spray" % "spray-servlet" % "1.1-M7",
"com.typesafe.akka" %% "akka-actor" % "2.2-M3",
"com.typesafe.akka" %% "akka-slf4j" % "2.2-M3",
//Servlet API?
//"org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" artifacts Artifact("javax.servlet", "jar", "jar"),
"javax.servlet" % "javax.servlet-api" % "3.0.1" % "provided",
"ch.qos.logback" % "logback-classic" % "1.0.12"
)
resolvers ++= Seq( "snapshots" at "http://oss.sonatype.org/content/repositories/snapshots",
"spray repo" at "http://repo.spray.io",
"typesafe repo" at "http://repo.typesafe.com/typesafe/releases/",
"releases" at "http://oss.sonatype.org/content/repositories/releases")
I get these same 12 errors no matter what I try to use for the servlet API (or maybe it's not the Servlet API at all?):

I'm truly at a loss as to what the proper dependencies are, and they're not exactly spelled out on the spray.io site. Or I'm dumb and can't figure out what the dependencies are.

Answer 1

Aha, turns out that the git master branch has newer, breaking changes in it, and so the examples aren't valid for any released artifacts. Using a tag in the repo, in my case 1.1-M7 made everything happy again.
Herp derp.
