It appears 0.20.2 has a hard-coded path in a ruby Makefile? Granted, this is built on Mac OS X. See the end of this gist: https://gist.github.com/johnnyutahh/d6f6844ff36a05b01ac7 I see some build problems here, but at first glance they seem different: http://notmuchmail.org/pipermail/notmuch/2015/020720.html Are builds for tagged versions in the master branch supposed to generally be "solid", including for OS X? Or should I not expect such things. ~Johnny
