My issues running course materials with cabal

cabal terminal output

I'm following the book instructions to try and get their repo set up. My current GHC version is 8.0.2.

Here's what I did, as per the instructions:

$ cabal update
$ cabal get hid-examples
-- seems to work OK, I get the package in its own directory.

$ cabal sandbox init
-- seems to work OK, I have a cabal.sandbox.config and a .cabal-sandbox file in my directory

$ cabal v2-install --only-dependencies
Resolving dependencies...
Up to date
Warning: You asked to install executables, but there are no executables in
targets: . Perhaps you want to use --lib to install libraries instead.
-- this is not the first time I run this command and I lost the output from the first time.
-- is everything okay here? How could I tell? The book does not suggest the --lib option.

$ cabal configure
Warning: The configure command is a part of the legacy v1 style of cabal
usage.
-- (more info about switching to new-configure omitted)

Resolving dependencies...
Warning: solver failed to find a solution:
Could not resolve dependencies:
[__0] trying: hid-examples-0.4 (user goal)
[__1] next goal: base (dependency of hid-examples)
[__1] rejecting: base-4.9.1.0/installed-4.9... (conflict: hid-examples =>
base>=4.10 && <4.13)
[__1] fail (backjumping, conflict set: base, hid-examples)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: hid-examples, base
Trying configure anyway.
Configuring hid-examples-0.4...
cabal: Encountered missing dependencies:
Chart >=1.8 && <1.10,
-- (omitting rest of dependency list)

-- then running cabal (new-)build gives the same issue with the base dependency.
