Your "hello world" code is correct.

Is it Windows Vista? "More people":http://stackoverflow.com/questions/1352371/nsinstall-bad-file-number-error-on-vista complained about it trying to build Mozilla Firefox on Vista. It seems there is an issue with long absolute paths, check if it's your case.

Ops... wait, now I saw the error number in the output you posted :-P

Well... the code you're trying to build still correct, the error is related with your build environment. I'll post here if I find something more conclusive.
