Cabal install failure - Githubissues

Hey,

I'm having trouble getting Snap installed. I'm completely new to Haskell, so it is highly probable that it's something I'm doing wrong, but it seems that this commit would have fixed the issue I'm experiencing:

https://github.com/snapframework/snap-templates/commit/c0805124bd7b94ff4ec73f063ee0e17e75d4211c

Specifically, this part of the commit:

 -    template-haskell    >= 2.2     && < 2.11,
 +    template-haskell    >= 2.2     && < 2.12,

Here's what happens when I try to install Snap:

➜  cabal update
Downloading the latest package list from hackage.haskell.org
Skipping download: local and remote files match.

➜  cabal install snap
