Created attachment 861045 [details] build log Trying to emerge dev-util/cmake-3.26.3 fails in the install phase with the error 'make: *** [Makefile:120: install] Illegal instruction'. Same error with version 3.25.3. I am able to install the latest upstream release using the official instructions just fine.

Mistake on my side. I had a wrong march/mtune inside my CFLAGS that was causing broken executables to be built.
