scala> import org.scalacheck.Prop.forAll                                      
error: error while loading Prop, Scala signature Prop has wrong version
 expected: 5.0
 found: 4.1 in /opt/scala-2.8/lib/scalacheck.jar(org/scalacheck/Prop.class)

It's the the actual scala-2.8, and scalacheck was updated with sbaz immediately before (sbaz update; sbaz upgrade).

Is scalacheck for scala-2.8 under development, and not suitable for 2.8, or what might be the problem?

Do I have to get the sources, and recompile scalacheck by myself开发者_C百科?

You can get it from the project page. It seems that it is not updated to 1.7 in sbaz yet.

ScalaCheck 1.7 for Scala 2.8 should be available in sbaz now.
