While attempting to port the Syfco project
(https://github.com/reactive-systems/syfco and following) instructions from the
handbook (https://docs.freebsd.org/en/books/porters-handbook/book/#using-cabal)
I am getting this error:

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: syfco-1.2.1.2 (user goal)
[__1] next goal: base (dependency of syfco)
[__1] rejecting: base-4.16.3.0/installed-4.16.3.0 (conflict: syfco =>
base>=4.7 && <4.13)
[__1] fail (backjumping, conflict set: base, syfco)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: syfco, base
