Looking at the commit history for this port, and the build history in the buildbots, I think its safe to say this port has not been really maintained for a long time now, the last meaningful commit was probably 10 years ago. I suspect if its possible at all, getting this port back working on recent OS versions with newer gcc versions etc. will be a lot of work for someone…
