Seems conky now needs gperf installed at build time see arch issue (https://bbs.archlinux.org/viewtopic.php?id=295694).
Ha. Just came here to post this too :) You were the first.
Since this is an issue upstream, we'll wait for Arch's fix. Thanks
Arch took too long, come get conky-1.20.2-1.1
thx! ;-)
