What steps will reproduce the problem? build using cabal from a git checkout What is the expected output? What do you see instead? successful build; error message is: Assistant/WebApp/Form.hs:15:8: Could not find module `Yesod.Form.Fields' It is a member of the hidden package `yesod-form-1.2.0'. Perhaps you need to add `yesod-form' to the build-depends in your .cabal file. What version of git-annex are you using? On what operating system? git checkout commit 90b62db1defdd223294935ec0bbaac883cd20c04 on OS X Lion Please provide any additional information below. adding yesod-form to the build depends in git-annex.cabal does indeed fix the problem! > [[done]] --[[Joey]]
