Hard-Coded ScalaCheck Version Broken in Scala 2.7.2

                 Key: BUILDR-210
             Project: Buildr
          Issue Type: Bug
          Components: Test frameworks
    Affects Versions: 1.3.3
            Reporter: Daniel Spiewak
            Priority: Blocker
             Fix For: 1.3.4

With the release of Scala 2.7.2, the *hard-coded* ScalaCheck version (1.3) is no longer sufficient.
 This version of ScalaCheck depends upon a method which no longer exists within the Scala
standard library.  For the sake of Google, this is the precise error message:

    Exception "java.lang.NoSuchMethodError: scala.Stream$cons$.apply(Ljava/lang/Object;Lscala/Function0;)Ljava/lang/Object;"
raised on argument generation.

The solution is to use ScalaCheck 1.4 instead of 1.3.  Just to make things even more fun,
Specs 1.3.1 does not work with ScalaCheck 1.4 (only with 1.3 and earlier).  This problem is
fixed in the (still forthcoming) 1.3.2 release, but until then, there will apparently be no
running tests under Scala 2.7.2 using Specs and ScalaCheck in conjunction.  Sucks to be me...

This is an absolute killer for me.  I use ScalaCheck quite extensively, which means that I
now have 300+ tests which now crash where before they ran fine.  If we can't get a release
which either increments the hard-coded version or provides a configurable option, could we
at least get a patch which can be applied manually to do the same?
