I think this is just the way it works currently, since cabal only tracks the installed package and version, but not if profiling was enabled. I always have my ~/.cabal/config set to install profiling libraries to avoid this problem. That doesn't help you now though. The easiest thing to do is probably to remove your sandbox and start from a blank slate.<br>

It's a cabal project and I've been using cabal-dev for sandboxing. Normally I would just run `cabal-dev install` to get everything built and the executables "installed" in ./cabal-dev/bin.
