[scala-tools] Can't install 2.7.4 final plugin under latest Eclipse 3.4 SR2 on OS X

Hi

When I try to install the plugin Eclipse complains about a requirement mismatch:

Cannot find a solution satisfying the following requirements org.eclipse.ui [3.4.2.M20090204-0800].

I'm running Eclipse 3.4.2 build: M20090211-1700 

Is there a fix for this problem?

Thanks in advance :)
