Dependencies are out of date

On macos:

nix-shell fails to open a shell:

On linux, nix-shell succeeds, but cabal build fails:

[nix-shell:~/code/servant-reflex]$ cabal build
Warning: The package list for 'hackage.haskell.org' does not exist. Run 'cabal
update' to download it.
Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: testdriver-0.2 (user goal)
[__1] unknown package: webdriver (dependency of testdriver)
[__1] fail (backjumping, conflict set: testdriver, webdriver)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: testdriver, webdriver

I (or a kind contributor!) need to bump the reflex-platform.nix reference to a more recent reflex-platform, and debug any remaining issues with the build, e.g. outdated dependencies.

On linux, using reflex-platform v0.9.0.2, I successfully entered nix-shell and ran cabal build

[nix-shell:~/github/imalsogreg/servant-reflex]$ cabal build
