Comment (by cdeil):

 I did the update to Astropy 1.3 in https://github.com/macports/macports-
 ports/pull/131

 However, just now, I realised that it's broken.

 Apologies for that!!!

 The reason, I think, is that erfa needs to be updated from 1.2.0 to 1.3.0:
 https://github.com/liberfa/erfa/releases/tag/v1.3.0

 I now see that {{{py-astropy}}} uses cfitsio, expat, wcslib also from
 other ports, so possibly those also need to be updated?
 {{{
 build.args-append   --use-system-cfitsio \
                     --use-system-expat \
                     --use-system-wcslib \
                     --use-system-erfa
 }}}

 @robitaille - Can you please comment what should be done to fix Astropy?
 I could make a PR once it's clear how to fix this.

 Isn't there some mechanism to prevent such mistakes for coupled ports?
 Is the requirement in Astropy on an exact version, or is it a minimal
 requirement?

 If there's no mechanism to really declare the required versions of other
 ports, then maybe a comment with a link to
 http://astropy.readthedocs.io/en/latest/install.html#external-c-libraries
 would be helpful?
