That thread mentions getting the Android emulator running and creating a hello world program on OpenBSD but I think required? linux emulation and so i386 and copying from a linux install. A recent Intellij is in ports which Android Studio Beta is based on and whilst I hope Gnome/KDE requirments for Linux are mis-prints and not on the OSX version maybe there's a chance it will work without Linux emulation like netbeans does compared to the pain of recompiling eclipse.
