Newbie: Can't understand cabal errors during install of hakyll

[Cyd Parser]

Hi Peder,

I'd recommend giving stack a try (https://github.com/commercialhaskell/stack).
I have found it easier to use than cabal-install. Many executables will
install just fine using `stack install <package-name>`. Packages that stack
has trouble creating a build plan for (like hakyll) can usually be
installed using the following:

stack unpack hakyll
cd hakyll-*
stack init
stack setup
stack install

`stack install` copies the resulting binaries to ~/.local/bin by default:
add that to your path.

Cheers,

cydparser
