Hi Andreas,
It's been a pleasure, due to the support from the upstream developers and from Steffen.
The libchealpix-dev, libhealipx-cxx-dev, and python-healpy packages should go in Astronomy-dev. python-healpy could conceivably also go in Astronomy, because it is useful for interactive use in Python interpreter.

That sounds good, but I didn't quite follow from the Wiki page what Sponsoring of Blends means. Could you please explain?
Best,

As a result, one of the unit tests runs indefinitely. The function converges and the unit tests terminate quickly and successfully on kfreebsd-i386 if we disable OpenMP. OpenMP is still enabled on all other platforms.
