It does, I just checked. I'm not sure why it's dangerous, xargs in
/tmp/ is dumb, and anywhere else you control and should be safe..

There is exactly one header file, and IMO packages should care enough
about their dependencies to not do silly things to get a single file
included.
It is in the .diff.gz, so apparently provided upstream.

+ ln -s . lua )
