This testing release only features the updated compile and profiling tools. We do not have the eclipse packages included within this release. TUV does not provide eclipse for Developer Toolset 2.0 on EL5. Unless any critical bugs are reported we expect to push this 'compiler only' version of Developer Toolset 2.0 into SL 5.10 contrib February 3. For more information on these updated compilers please review the upstream documentation: https://access.redhat.com/site/documentation/en-US/Red_Hat_Developer_Toolset/ 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> Pat -- Pat Riehecky Scientific Linux developer http://www.scientificlinux.org/
