You can download it from http://sourceforge.net/projects/xreal/files/ETXreaL/
This is a complete download. You don’t need any previous versions of ETXreaL.
EDIT: I replaced ETXreaL-0.3.0-20111106.7z with ETXreaL-0.3.0-20111110.7z that contains ETXreaL/etmain/*.so files so you don’t have to extract them. The pk3 files and binaries are still the same so there is no reason to update.
