https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: www-misc/mergelog-4.5-r2 has a configure.in file which has long been deprecated. Discovered on: amd64 (internal ref: tinderbox)
Created attachment 751730 [details] build.log build log and emerge --info
Bug is obsolete, autoreconf moves configure.in to configure.ac
