Hello while trying to build propellor on jessie, I got this error message


    picca@irdrx1:~/.propellor$ propellor
    Preprocessing executable 'propellor-config' for propellor-4.9.0...
    [105 of 120] Compiling Propellor.Property.PropellorRepo ( src/Propellor/Property/PropellorRepo.hs, dist/build/propellor-config/propellor-config-tmp/Propellor/Property/PropellorRepo.o )

    src/Propellor/Property/PropellorRepo.hs:17:37:
    No instance for (Typeable OriginUrl) arising from a use of `toInfo'
    Possible fix: add an instance declaration for (Typeable OriginUrl)
    In the second argument of `setInfoProperty', namely
      `(toInfo (InfoVal (OriginUrl u)))'
    In the expression:
      setInfoProperty p (toInfo (InfoVal (OriginUrl u)))
    In an equation for `hasOriginUrl':
        hasOriginUrl u
          = setInfoProperty p (toInfo (InfoVal (OriginUrl u)))
          where
              p :: Property UnixLike
              p = property ("propellor repo url " ++ u)
                  $ do { curru <- liftIO getRepoUrl;
                         .... }
