The binary packages. Here is an example for how we make sure that an ABI incompatible change to web-routes requires a rebuild of yesod, and that until that happens the user will not get the new web-routes package installed.

So the Debian Haskell team then has to update the apt package when there's an ABI mismatch (that is, a dependency has been updated or rebuilt with a new ABI)? Or is this done automagically somehow for the user? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
