Apart from the broken feature to dispaly AUR comments, the only issue with yaourt is tmpfs. Note, I'm using the plain makepkg approach as well as yaourt, but no other AUR tool. To workaround the tmpfs issue, you simply could add an alias, such as mine: alias naourt='echo "Not AnOther User Repository Tool";rm -rf /{.,}tmp/yaourt-tmp-$(id -un);yaourt --tmp /.tmp' However, I didn't try to build another/this DX7 clone, since my master keyboard is the first generation DX7 (brown metal case), I bought when I was a teenager, decades ago and nothing compares to it's output recorded with a RME card. I seriously doubt that an error such as "make: *** No rule to make target" is caused by using yaourt. Much likely it's either a broken PKGBUILD or an partial upgraded Arch Linux.
