[Haskell-cafe] Yesod and dependencies hell

[Никита Тимофеев]

For three days I can't compile dependencies for my project using
yesod, yesod-auth, yesod-persistent, persistent-template,
persistent-sqlite, persistent. When I varied version I received a
variety of broken dependencies: persistent (0.6.* vs 0.7.*), conduit
(0.1.* vs 0.2.*), conduit-pool, path-pieces, attoparsec and something
else. In this regard, I have a few questions. How to build these
packages together? And, Michael, why so bad?
