I don't know who actually pulls in gperf on my gentoo linux (it is installed), but in prefix, i cannot build coreutils-8.8 on a clean @system-only prefix. i get: make[2]: Entering directory `/opt/gentoo/var/tmp/portage/sys-apps/coreutils-8.8/work/coreutils-8.8/lib' GEN alloca.h GEN arg-nonnull.h GEN c++defs.h GEN warn-on-use.h GEN configmake.h GEN errno.h GEN fnmatch.h GEN getopt.h gperf -m 10 ./iconv_open-hpux.gperf > ./iconv_open-hpux.h-t gperf -m 10 ./iconv_open-irix.gperf > ./iconv_open-irix.h-t /opt/gentoo/bin/bash: gperf: command not found make[2]: *** [iconv_open-hpux.h] Error 127 this is x86-interix, but i guess it does not matter. if i manually merge gperf, it works as expected.
i'm not adding a hard dependency on gperf when only a few random non-linux systems need it
Please check the mtimes of lib/iconv_open-XXX.gperf and lib/iconv_open-XXX.h files. In 8.9 the .h is older than the .gperf file, which should assure that the .h files aren't regenerated from the .gperf files (Makefile rule).
