Astropy affiliated packages for Debian

[Vincent Prat <vinceprat@free.fr>]

Hi Ole,

I have successfully packaged version 0.1 of astroquery, and then noticed 
that version 0.2 were released.
It seems that the new release needs astropy-helpers (provided by 
upstream astropy, but apparently not packaged in Debian) to build.
Could you please consider packaging it (with astropy or separately) or 
help me to find a workaround?
Thank you in advance.

Regards,
Vincent
