Unresolved dependency with specs2 scalaz-stream 0.5a

Question

Since adding:

"org.specs2" %% "specs2" % "2.4.15" % "test" withSources() withJavadoc(),

To my build file I get

[warn]  Note: Unresolved dependencies path:
[warn]      org.scalaz.stream:scalaz-stream_2.10:0.5a
[warn]        +- org.specs2:specs2_2.10:2.4.15
...
[error] (*:update) sbt.ResolveException: unresolved dependency: org.scalaz.stream#scalaz-stream_2.10;0.5a: not found
