[Debian-astro-maintainers] Bug#755485: python-astropy: too low wcslib version in build-depends

[Julian Taylor]

Package: python-astropy
Severity: minor
Version: 0.4-3

python-astropy does not build with the version 4.20 stated in the build depends:

astropy/wcs/src/wcslib_wrap.c: In function ‘PyWcsprm_compare’:
astropy/wcs/src/wcslib_wrap.c:754:3: warning: implicit declaration of
function ‘wcscompare’ [-Wimplicit-function-declaration]
   status = wcscompare(cmp, &self->x, &other->x, &equal);
   ^
astropy/wcs/src/wcslib_wrap.c: In function ‘PyWcsprm_richcompare’:
astropy/wcs/src/wcslib_wrap.c:1700:9: error: ‘WCSCOMPARE_ANCILLARY’
undeclared (first use in this function)
         WCSCOMPARE_ANCILLARY,


updating to current unstable 4.23 seems to fix the build.
Please correct the version requirements to aid backports of the package.

Thanks,
Julian Taylor
