[Haskell-cafe] cabal sandbox using absolute path on symlinked dir

Hello Cafe, On Ubuntu, after creating a sandboxed project in a symlinked directory, cabal.sandbox.config contains absolute (canonical) paths of the directory, and not the symlinked paths. Is this a bug, and is there a way to correct that behavior? There is no way to move the project to a different place without recreating the whole sandbox. Best regards, vlatko
