+(Argh, this question fell into my backlog unnoticed!)
+
+These build flags depend on C libraries and stack can't install C libraries
+so enabling them would make the stack build not succeed on all systems.
+The build does #warn about features that are not enabled when building with
+the flags turned off.
+
+If you're able to install libdbus and libmagic, you should, and turn the
+build flags on.
