This is another reason why the package has not been promoted to extras repository. The latest EFL build breaks compatibility with previous versions. So we need to adapt the Carman packages to this new version. The same applies to all other packages built on the EFL stack.

Unfortunately, as you may have guessed by now, Carman has the same maintenance problem as Canola. Actually it's a bit worse, as it hasn't got any devs devoting their spare time to it. I will try to get the issue solved at least to get it working. But to be honest, don't expect any other bugs or features implemented for Carman.
