The 0.8.4 tarball is missing file man/libbsd.7 and the build system does not seem to want to install it yet, either (so not compile errors). I guess commit ba9e2a5a9cc097047517257383795a3335faea43 is missing extension of the dist_man_MANS variable?
Ah, yeah missed that. Fixed now locally will be included in the upcoming 0.8.5 which I will release in a couple of days at most. Thanks!
This should be fixed now in 0.8.5. Closing.
