python_test() { cd ${BUILD_DIR} || die nosetests-${EPYTHON} -v || die "Testing failed with ${EPYTHON}" ^^^^^^^^^^^ } Please don't play with internals like this. 'nosetests' is a wrapper, and eclass sets up environment properly, so the wrapper will choose correct implementation.
Created attachment 358640 [details, diff] patch to ebuild Please let me know if this patch is ok to commit. Changes: 1. enforced a single impl since sci-physics/root supports that only, 2. required USE=python on sci-physics/root, 3. fixed the nosetests invocation, 4. fixed EXAMPLES not to be compressed.
