https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-ruby/flexmock-2.4.2 installs the same files with USE=doc. Discovered on: amd64 (internal ref: ci) NOTE: To reproduce this issue: 1) Install the package without USE=doc 2) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist1 ) 3) Install the package with USE=doc 4) Put the list of the installed files into a file ( qlist -e PACKAGE:SLOT | sort | uniq > /tmp/qlist2 ) 5) See the diff between the two files ( diff -ru /tmp/qlist_1 /tmp/qlist_2 ) On this machine: - the installed files without USE=doc are 118 - the installed files with USE=doc are still 118 Usually USE=doc is supposed to build and install documentation files, so a build with USE=doc should install more files. If that's not the case, feel free to close. This type of report comes from a check that is a bit outside of the tinderbox, that's the reason because build.log was not provided (however in cases like these the build.log doesn't help much) but if you need further help to diagnose this issue feel free to ask.
