The Get lines for ppa.launchpad.net are for the othermirror you specified.

There is only ossim for wily, most UbuntuGIS packages are for the LTS
releases.

Start by reading the relevant sections of the git packaging walkthrough:

http://pkg-grass.alioth.debian.org/policy/packaging.html#git-walkthrough

Because you're using a chroot for a non-standard distribution and this
hasn't been configured in debian/gbp.conf, you need to specify the
distribution with the -ubuntugis suffix to have git-buildpackage use the
correct chroot (i.e. --git-dist=wily-ubuntugis). This is documented in
the 'Building the package' section:

http://pkg-grass.alioth.debian.org/policy/packaging.html#git-build-package
