Updated packages have been posted for testing:

We have successfully compiled the Developer Tools suite for SL 6.

This includes all compilers and the Eclipse IDE.

We have published the updated versions of these tools for testing in the
traditional sl-testing repo.  If there are no significant issues
reported before May 1, we will release these into the SL Developer
Tools repo with the necessary updateinfo entries.

Due to package changes upstream, the Developer Tools 2.1 components
are considered RPM upgrades to 2.0 packages.  They cannot be installed
in parallel.

You can install this update for testing via the sl-testing repo on
your SL system:
   yum --enablerepo=sl-testing update <package you wish to test>
