Hmm, well it started life in a .zip file, so yeah, there just might've been DOS code in there that I wasn't aware of. Will try fixing, but I'm now concerned similar problems may exist throughout :/
Will try and report back.
EDIT: Well, it starts configuring at least, thanks Uelsk8s. Now it decides to break elsewhere :/

I'm uncertain whether or not that'll make any changes to vpackager's success, but I'll test that now.
EDIT2: Nope, vpackager still insists "Unable to process source - please build manually"
