Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] next goal: libsystemd-journal (user goal)
[__0] rejecting: libsystemd-journal-1.4.3 (conflict: pkg-config package
libsystemd>=209, not found in the pkg-config database)
[__0] rejecting: libsystemd-journal-1.4.2, libsystemd-journal-1.4.1,
libsystemd-journal-1.4.0, libsystemd-journal-1.3.4, libsystemd-journal-1.3.3,
libsystemd-journal-1.3.1, libsystemd-journal-1.3.0, libsystemd-journal-1.2.0,
libsystemd-journal-1.1.0, libsystemd-journal-1.0.0 (constraint from user
target requires ==1.4.3)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: libsystemd-journal
