Ghc version:

Cabal version:

Installed versions of packeges which react-haskell depends:

• base 4.8.1.0
• transformers 0.4.2.0
• monads-tf 0.1.0.2
• deepseq 1.4.1.1
• lens-family 1.2.0
• void 0.7, 0.7.1
• aeson 0.9.0.1, 0.10.0.0
• text 1.2.0.3
• unordered-containers 0.2.5.1

Maybe this is the report from Cabal hell? I am trying different versions and the result is the same.

I also had a problem building with no instance of eq jsstring a while back, then gave up.

I did some hacking on this repo nearly a year ago and this error rings a bell. There's a good chance you'll need to just fix it yourself. Fortunately you're barely even in the first circle of cabal hell, because there's only one package left to install, and it's (only slightly) broken rather than the dependency structure. Good luck!
