 this port apparently is not compatible with clang. Therefore the port must

 The alternative compiler could be `ghc`, however I cannot verify if its
 current Macports version builds this port (since it is not yet fixed for
 PPC). As I recall, defining it to build with `gcc` has been both done in
 Macports with the earlier version of the port, as well as on FreeBSD.
