Now that it's getting clearer, maybe I'll be able to make a Darwinports port file, although having to patch src/tools/install.neko may be a problem. It would also be easier if you made minor release versions.
Yes this can be modified.
Would you be motivated enough to compile and package haXe+Neko OSX releases for the official website ? I can give you the rights to upload content.
