Building from /dev/stdin work fine on Macbook (useful to use sed to edit stream).

Ended up having NOTHING to do with PHP versions. Still not sure why it worked on 5.3.8 on Mac, but not the same version on lucid, but found an alternative:
This works since
file_get_contents('php://stdin')doesn't fail like it does with/dev/stdin.Reference: http://stackoverflow.com/questions/3249427/how-to-process-stdin-to-stdout-in-php
