When testing dd-rescue on arm64, I noticed that the build tries to use git, but fails. The package still install ok and works as expected. gentoo-aarch64 /var/db/repos/gentoo/sys-fs/dd-rescue # ebuild dd-rescue-1.99.13-r1.ebuild merge * dd_rescue-1.99.13.tar.bz2 BLAKE2B SHA512 size ;-) ...

From the upstream Makefile: ``` ID = $(shell git describe --tags || cat REL-ID) DEFINES = -DVERSION=\"$(VERSION)\" -D__COMPILER__="\"$(COMPILER)\"" -DID=\"$(ID)\" # -DPLUGSEARCH="\"$(LIBDIR)\"" ``` This could be done a lot more elegantly... at the very least it should silence the error message when git is not installed. But yes, it is harmless.
