Re: Backporting matplotlib and its dependencies (Was: Sagemath Build-Depends backported - unfortunately build error (Was: Help needed to backport ipywidgets ... (Was: Backporting sagemath))]
Ah, I didn't realise it would be this hard. You could try backporting 1.5 instead of 2.0, that is what Sage themselves are using:
https://people.debian.org/~thansen/debian-sage-7.4-status.html (see the matplotlib row)
If that is not allowed by backports policy, I'm not sure of the best way forward. There's a few options, none of which seem nice:
- patch 1.4, to simply not omit the "FutureWarning". However, from the error message it sounds like this would continue to make Sage fail, because they are expecting the "future behaviour" that 1.4 doesn't yet do.
- patch 1.4, to perform the future behaviour, by applying a patch from 1.5. However this might break other programs that use matplotlib. :(
