This is not needed since F11, so unless you want to build this package for EL5, you should remove it.

> $RPM_BUILD_ROOT
Can you choose one style of variables? I suggest to replace this by %{buildroot}.

> nothing provides xz-utils needed by debbuild-0.10.1-1.fc22.noarch
AFAIK it is needed because of/usr/bin/xz which are in "xz" in Fedora. 

I would suggest to change Requires of dpkg-dev to:
Recommends: dpkg-dev
as it provides /usr/bin/dpkg-architecture which is used if available and greatly enhance user experience. But this program will run without it.

The main reason I didn't use Recommends is because Enterprise Linux and Fedora 21 don't support resolving weak dependencies. I've now added a conditional to switch between Requires and Recommends based on whether it is EL or Fedora versions lower than 22. I've also fixed the xz dependency.

I've removed the EL5 specific stuff since EL5 is ancient and I don't really care about that release anyway.

Here's the updated SRPM URL: http://kinginuyasha.enanocms.org/downloads/debbuild-0.10.1-2.fc22.src.rpm

The Spec URL remains the same: http://kinginuyasha.enanocms.org/downloads/debbuild.spec

APPROVED

The diff in SRPM is very minor issue, just be sure you are uploading SRPM with correct changelog in dist-git.
