I am not surprised, there is a lot of churn in the ports tree at the moment and a ton of things are failing to build.
If you want to send the PBI module in to the PC-BSD project, I can throw it on our build server and try it there. Kris tries to actively apply pending fixes/patches for things in our ports tree on the build server during situations like this (I.E. apply the patches for ports that are just waiting for official adoption in the FreeBSD ports tree), and we might get a working PBI out of it.
