We already have a module for games/wesnoth, and our build server will automatically build the latest version once it gets going again. Recently, the PBI build servers have been turned off a number of time in order for the development snapshots of PC-BSD 9.1 to be built instead, which is why we are now a bit behind in releasing the latest PBI versions. We are looking into using an alternate server to built the testing snapshots, which will let the PBI build servers work without these constant interruptions.We should be switching over to this new setup here soon, but until then, you can either build the newer version of Wesnoth with EasyPBI (you can even use our module if you like!) or just wait for the new version to be released
Thanks for your patience!
