Can't satisfy dependencies in projects created by stack

[mineo]

Here's what I did:

GHC in /usr/bin is 7.10.1, I've previously built 7.10.2 for stacks lts-3.5 resolver with stack setup. I think stack itself is using the latter version of GHC to build things.

/Edit: Sorry, forgot the output of ghc-mod debug:

and ghc-mod --version:

ghc-mod version 5.4.0.0 compiled by GHC 7.10.1

[DanielG]

You need to recompile ghc-mod against GHC 7.10.2.

I've opened https://github.com/DanielG/ghc-mod/issues/726 for tracking giving better error messages for this case. Spewing errors like this for version mismatches is pretty awful, this took me a while to track down.
