Well, that’s annoying. I wasn’t able to get Pineapple News working in Haiku. After getting past the registration, it runs into file permission problems. Seems like it can’t read or write its own files, and when it creates a directory for working storage, it makes it unusable (no X flag to let you go inside the directory). Even if you copy the Pineapple folder onto your desktop and make everything writeable, it fails whenever you try to do anything. I suspect a Haiku / BeOS difference somewhere.
Anyway, I made a pineapplenews-0.9.13-1-x86_gcc2.hpkg package, which you can get on my BeShare or at http://web.ncf.ca/au829/BeOS/ Not too useful; you can run it, but it fails with an error message whenever you try to do something.
