This never happened to me. It is easy enough to write a custom build environment pkgbuild and put it on the aur, and use an aur helper like pacaur to cache the git repos. I tried gentoo on a vm after getting frustrated and wanting to do a configure / make / install on Samba, but after a few hours compiling coreutils I gave up and concluded that it is just a silly waste of electricity for everyone in the world to recompile the same binaries, or slightly different ones with one feature change that might break interactions with a dozen other applications. Someone else can just build optimized binaries for my architecture and were good, the last 5% isn't worth the power bill, it is cheaper to just buy 5% faster parts.
But I can't go to anything but Arch. I have opensuse on my grandparents PC and I so desperately want to put Arch on it since managing the legacy in any of the distros that aren't Arch (ie, /boot/grub and /boot/grub2 on a standard install, init scripts mixed with systemd units, xinetd + systemd, etc) makes me feel like its 2003 instead of 2013. I sometimes put dual boot Ubuntu / Windows on some of my freelance IT customers to let them pick what they like and keep the other as a failsafe, but tweaking Ubuntu now feels like a chore. I still giggle with glee when installing a new Arch box though.
