On a fresh install, configure step fails on missing autoconf. Reproducible: Always
Please post emerge --info and attach the build log (standard bug procedure). It builds just fine for me without autotools installed.
Didn't save the build.log... This was on a fresh stage3 install. Going through my emerge.log I see the crash, then the install of autoconf (pulls in autoconf-wrapper and m4) then the re-attempt at installing rcs working... Unmerging autoconf, autoconf-wrapper and m4 now and attempting to re-emerge rcs does not reproduce the bug...
