The following patch should do the trick:

I wonder about executing these debian/rules commands on a 'live' system though, rather than using sbuild to build the package in a chroot environment. These rules are tested and expected to run in a temporary build environment, and if your local system actually had a file in that location that you cared about, building the .deb "by hand" would destroy it -- and perhaps other files you care about.

You're not the first to report this specific error but I really think the better answer is to use sbuild to build debs.

Thanks
