sys-kernel/gentoo-kernel does not have direct or indirect depenency on dev-lang/perl. But it can run some perl scripts while building. If perl is not yet installed in the system, emerge gentoo-kernel will not install it before building of the gentoo-kernel package and it could fail. Reproducible: Always Steps to Reproduce: Example of emerge on system not having perl installed yet and emerge not installing it while emerging gentoo-kernel: 163dea883cd6 / # which perl which: no perl in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin) 163dea883cd6 / # emerge -vpk gentoo-kernel !!! /etc/portage/binrepos.conf is missing (or PORTAGE_BINHOST is unset), but use is requested. !!! /etc/portage/binrepos.conf is missing (or PORTAGE_BINHOST is unset), but use is requested.

Please can you post a full build.log and the output of emerge --info
Created attachment 891309 [details] build log
"emerge --info" is there in the original message. Is there reason for the full kernel build log? I provided a part where it clearly failed while trying to use perl. But anyway, attached the log too.
Stumbled onto this myself. The lines leading to the error are # GEN lib/oid_registry_data.c perl /var/tmp/portage/sys-kernel/gentoo-kernel-6.10.7/work/linux-6.10/lib/build_OID_registry /var/tmp/portage/sys-kernel/gentoo-kernel-6.10.7/work/linux-6.10/include/linux/oid_registry.h lib/oid_registry_data.c /bin/sh: 1: perl: not found make[4]: *** [/var/tmp/portage/sys-kernel/gentoo-kernel-6.10.7/work/linux-6.10/lib/Makefile:336: lib/oid_registry_data.c] Error 127 make[3]: *** [/var/tmp/portage/sys-kernel/gentoo-kernel-6.10.7/work/linux-6.10/scripts/Makefile.build:485: lib] Error 2 But I will attach emerge --info and the build log.

I think this requirement for perl is a result of your savedconfig. Do you happen to know which of your config options adds this requirement? I'm not sure we want to add a dependency on perl for everyone if it is not required by our default configuration.

The build log is essential because we need to know what happened in the prepare and configure phases to eventually result in a failure in the compile phase
Created attachment 901712 [details, diff] diff between kernel config for versions 6.10.6 and 6.10.7 That makes sense. I have never had to have perl installed when building the kernel until the latest release. Looking at the build log, it expectedly says that it is using /etc/portage/savedconfig/sys-kernel/gentoo-kernel for the config. That one was done manually, when 6.6.35 was brand new. Since I've only now stumbled across this perl thing, it has to be something in the diff between 6.10.6 and 6.10.7. I'm uploading the diff between those two kernel configs.
Looking at the build log and your diff I suspect the option causing the perl requirement is CONFIG_CRYPTO_POLY1305. Can you confirm this?
Actually, CONFIG_CRYPTO_POLY1305 is part of our default config, so we should BDEPEND on perl
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=660b9cf9f08fd27fca32f1bd1bd8e95ee7a635bc commit 660b9cf9f08fd27fca32f1bd1bd8e95ee7a635bc Author: Andrew Ammerlaan <andrewammerlaan@gentoo.org> AuthorDate: 2024-08-30 19:41:18 +0000 Commit: Andrew Ammerlaan <andrewammerlaan@gentoo.org> CommitDate: 2024-08-30 19:43:32 +0000 kernel-build.eclass: BDEPEND on dev-lang/perl Some config options (that we enable by default, e.g. CONFIG_CRYPTO_POLY1305) cause perl scripts to be run during the build.

For the record, disabling CONFIG_CRYPTO_LIB_POLY1305 is not enough. The error still looks the same. When I confirm which part of the config was the problem, I will report back.
Huh... I went all the way back to my 6.10.6 kernel config. Still the kernel build system wanted to invoke perl.
