You receive this bug because this package does not respect my system's AR (x86_64-pc-linux-gnu-ar) and calls directly /usr/bin/ar The possible solutions to fix this issue are: 1)Fix the buildsystem, if you can; 2)inherit toolchain-funcs and use tc-export AR 3)inherit toolchain-funcs and use emake AR="$(tc-getAR)" From the build log: ar cr libreadline.a readline.o vi_mode.o funmap.o keymaps.o parens.o search.o rltty.o complete.o bind.o isearch.o display.o signals.o util.o kill.o undo.o macro.o input.o callback.o terminal.o text.o nls.o misc.o compat.o xfree.o xmalloc.o history.o histexpand.o histfile.o histsearch.o shell.o mbutil.o tilde.o
should be all set now in the tree; thanks for the report! Commit message: Export AR ourselves to use a better default http://sources.gentoo.org/sys-libs/readline/readline-6.2_p5.ebuild?rev=1.1
