I'm new to Yesod and stack. I initiated the quickstart project per the instructions on the website, however, after I run `stack exec -- yesod devel`, everything seems to be fine, except for the last line in the console: `yesod: /usr/local/haskell/ghc-7.10.3-x86_64/lib/ghc-7.10.3/settings: openFile: does not exist (No such file or directory)`. Then, whenever I try to connect to localhost://3000, I get \"the Application isn't built. we'll keep trying to refresh every second.\", with no extra output being shown on the console.\r\n\r\nI have no idea why it seems to be trying to access a file that doesn't exist. I don't have any ghc installation at `/usr/local/haskell` now, and the 7.10.3 version of ghc should have been installed locally into the project directory via `stack build`. The only reason I can think of is I indeed previously installed ghc 7.10.3 via Haskell Platform https://www.haskell.org/platform/#linux-generic to `/usr/local/haskell`. However, I already tried to delete everything that comes with this installation, including this folder and all the symlinks it created in the /usr/local/bin folder. So it's likely that there is still some (global) configuration file remaining in my system that says ghc 7.10.3 is installed at `/usr/local/haskell/ghc-7.10.3-x86_64/lib/ghc-7.10.3/`, however I'm at a loss as of where to find this configuration file and change it. Any idea? I understand I should have used stack from the beginning and not installed Haskell Platform on my system, but I didn't know.\r\n\r\n- System: Ubuntu 14.04 64-bit.\r\n- Stack: version `Version 1.0.0, Git revision 3bc26237b5b3c387b8fd564459ea4dd88fd58b30 (2939 commits) x86_64`/\r\n- Yesod: yesod-bin version: 1.4.16.1"},"comment":{"url":"https://api.github.com/repos/yesodweb/yesod/issues/comments/206154530","html_url":"https://github.com/yesodweb/yesod/issues/1135#issuecomment-206154530","issue_url":"https://api.github.com/repos/yesodweb/yesod/issues/1135","id":206154530,"user":{"login":"snoyberg","id":49415,"avatar_url":"https://avatars.githubusercontent.com/u/49415?v=3","gravatar_id":"","url":"https://api.github.com/users/snoyberg","html_url":"https://github.com/snoyberg","followers_url":"https://api.github.com/users/snoyberg/followers","following_url":"https://api.github.com/users/snoyberg/following{/other_user}","gists_url":"https://api.github.com/users/snoyberg/gists{/gist_id}","starred_url":"https://api.github.com/users/snoyberg/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/snoyberg/subscriptions","organizations_url":"https://api.github.com/users/snoyberg/orgs","repos_url":"https://api.github.com/users/snoyberg/repos","events_url":"https://api.github.com/users/snoyberg/events{/privacy}","received_events_url":"https://api.github.com/users/snoyberg/received_events","type":"User","site_admin":false},"created_at":"2016-04-06T06:51:21Z","updated_at":"2016-04-06T06:51:21Z","body":"It does seem like a (reasonable) case of some paths getting hard-coded to the original GHC location.
