[Debian-med-packaging] Bug#1022048: patsy: FTBFS with Python 3.11 as a supported version

[Graham Inggs]

Source: patsy
Version: 0.5.2-2
Severity: important
Tags: ftbfs fixed-upstream
User: debian-python at lists.debian.org
Usertags: python3.11
Control: affects -1 src:statsmodels

Hi Maintainer

patsy will FTBFS once Python 3.11 is added as a supported version.
I've copied what I hope is the relevant part of the log below.  This
appears to be fixed in the upstream 0.5.3 release.

You can verify this by installing python3.11 from testing or unstable
and adding the following line to debian/rules:
export DEBPYTHON3_SUPPORTED=3.10,3.11

This affects at least statsmodels in dependency level 6 of the Python
3.11 transition (#1021984).

Regards
Graham
