https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sys-apps/i2c-tools-4.2 uses a probably incorrect DISTUTILS_USE_SETUPTOOLS value. Discovered on: amd64 (internal ref: tinderbox)
Created attachment 721888 [details] build.log build log and emerge --info
* Messages for package sys-apps/i2c-tools-4.2: * QA Notice: DISTUTILS_USE_SETUPTOOLS is not used when DISTUTILS_OPTIONAL * is enabled.
