I'm not in a position to test, but I think we need an upper bound of <=dev-haskell/wai-logger-0.3.2. The build system will accept anything, so you should only need to fudge the (R)DEPEND. The module hierarchy was restructured in wai-logger-2.x, thus the error.
Tree has a latest dev-haskell/http-reverse-proxy-0.4.2, should work fine.
