[Debian-astro-maintainers] Bug#844525: astropy FTBFS: version dependency on wcslib-dev is too loose

[Sergio Gelato]

Package: python-astropy
Version: 1.2.1-1

In trying to backport this version of astropy to jessie, I discovered that
it doesn't build against wcslib-dev 4.24 as advertised in debian/control.

The reason is that astropy/wcs/src/wcslib_wrap.c and astropy/wcs/wcs.py
both refer to WCSHDO_P14 which was only introduced in wcslib 5.13. 
Incidentally, that means the statement in astropy/wcs/wcs.py that
"versions 5.8 and later on the 5.x series are known to work" is of
questionable accuracy; I guess upstream will need to be told.

Browsing through version control I see that this broke in astropy 1.1.2.
(I'll probably backport 1.1.1 instead, since my actual requirement is (>= 1.0)
and upgrading wcslib in jessie risks breaking other things.)
