Cabal silently fails on OS X when installing ekmett/linear

[Mokosha]

Running the command cabal install linear fails silently when running on OS X. I've tried to run it in both a blank sandbox and globally, and both fail with the same error message:

$ cabal install linear
Resolving dependencies...
cabal: Could not resolve dependencies:
Dependency tree exhaustively searched.

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.

The same command works on 12.04 Ubuntu Linux without problems.

I am using OS X 10.9.2, GHC 7.7, and cabal 1.20.0.1

This is the same as #1855 and fixed in master. Temporary workaround is to say

cabal install linear --constraint="transformers-compat +transformers3"

Thanks! Sorry about the duplicate.

@Mokosha No need to apologize. It's not so easy to recognize this as a duplicate.
