Bug#809117: haskell-pango: FTBFS when built with dpkg-buildpackage -A (Haddock failed)

[Santiago Vila]

Package: src:haskell-pango
Version: 0.13.1.0-4
User: sanvila at debian.org
Usertags: binary-indep
Severity: important

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(i.e. only architecture-independent packages), and it failed:

Haddock failed (no modules?), refusing to create empty documentation package.

--------------------------------------------------------------------------------

Sorry not to have a fix, as I am reporting many bugs similar to
this one. The common hints are:

* If the only architecture-independent packages are dummy transitional
ones and they were released with jessie, the easy fix is to drop them
now.

* When using "dh", it is allowed to use (independently)
optional targets override_dh_foo-arch and override_dh_foo-indep
(for several values of "foo").


Once that both "dpkg-buildpackage -A" and "dpkg-buildpackage -B" work
properly, the package would be suitable to be uploaded in source-only
form if you wish.

Thanks.
