Created attachment 376398 [details, diff] Patch to conditionalize call to python-single-r1_pkg_setup When setting USE="-python" and PYTHON_SINGLE_TARGET="", which should be allowed per REQUIRED_USE and the actual deps used, this package fails to build due to an unconditional call to python-single-r1_pkg_setup(). The attached patch fixes this issue.
Fixed. Thanks for the patch.
