Thanks so much for that - I went and checked the GCC build I'd already done and found that it does indeed appear to not work as expected, the logic seems to be there and appears to trigger when run with: [samuel@qan02 ~]$ eb GCC-4.9.2.eb -f The logs say: == 2015-08-07 13:58:27,549 main INFO Command line: --buildpath=/usr/local/easybuild/build --force --installpath=/usr/local/easybuild --modules-tool=Lm od --optarch=native --prefix=/usr/local/easybuild --repositorypath=/usr/local/easybuild/ebfiles_repo --robot-paths=/usr/local/src/INTEL:/usr/local/eas ybuild/local-easybuild/: --sourcepath=/usr/local/easybuild/sources --tmpdir=/dev/shm GCC-4.9.2.eb [...] == 2015-08-07 13:58:28,086 main.Dummy INFO _set_optimal_architecture: using native as optarch for Intel.
