See https://github.com/wjt/bustle/commit/941806b1cf373685429170acd4d65cbf77dd682c . Apparently the Control.Monad.Except is only in said version and up. Otherwise the build dies as follows: --- >>> Compiling source in /var/tmp/portage/dev-util/bustle-0.5.1/work/bustle-0.5.1 ... ./setup build Building bustle-0.5.1... Preprocessing executable 'bustle' for bustle-0.5.1... Bustle/Loader.hs:29:8: Could not find module ‘Control.Monad.Except’ --- On a sidenote, there is also a 0.5.2 version. Reproducible: Always
Nice catch! Pushed as: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=7ddd1b287eb10473867dec11aad2b058f131fc96 Thank you!
