This may be helpful; I have a xfstests build environment here:

git://git.kernel.org/pub/scm/fs/ext2/xfstests-bld.git

It will automatically pull down the xfstests and xfsprogs from
git.kernel.org, and builds xfstests in a hermetic environment (i.e.,
it doesn't depend on version of xfsprogs, libacl, libaio,
etc. installed on the build system).  I set this up back when I was
doing most of my work using Ubuntu LTS 10.04, and the positively
ancient versions of libacl, libaio, xfsprogs-dev, etc., weren't
compatible with the bleeding edge of xfstests.

So I used this build environment so I wasn't dependent on the
vagrancies of whatever happened to be in Ubunutu LTS 10.04.

The makefiles in xfstests-bld will also generate a tar file containing
the necessary xfstests and xfsprogs binaries which I could then drop
into a debootstrap environment (I'm currently using a x86-32 Debian
unstable chroot) which I then use in my KVM image.  So it allows me to
get and build the very latest version of xfstests from git.kernel.org
in a highly automated fashion.
