The liblrdf port currently does not have a maintainer. As a result, it is
more likely to have unresolved issues, not be up-to-date, or even be removed in
It is for application Hydrogen
I think it is "normal" and does not cause any troube right now. Latest version is 0.6.1 in upstream.
Another 3842 ports have maintainer set to ports@FreeBSD.org.
Maybe some day a heavy user of liblrdf (or Hydrogen) will step up and adopt this port ;)
