It is thus a yes/no case, where either you can use the compatibility mode if you are not using the unsupported modules, or you have to adjust your code. 

Exactly, and that's not something I'm very much interested in testing in something that's not a stable release :)

Anyway, I figured out why eigen 2 doesn't build with clang. Apparently a C++ specialisation error in a single file. I'm not sure I understood it completely, but googling the error led me to a very simple solution that allows the build to complete (hopefully without introducing any regressions). A patch file and modified Portfile are attached to this message.

Heh, for the moment I don't have anything like a Portfile, neither for Calligra nor for the 2 or 3 dependencies I had to install outside of MacPorts ... but who knows. In any case I'll post an update when I think things are ripe. I hope the build process will be as standard as possible (and strive to get any adaptations accepted upstream) so making a Portfile ought to be easy enough for anyone accustomed to do so.
