[Python-modules-team] Bug#967025: python3-yaml: Build dependency on libyaml needs to be versioned (for 5.3.1-2)

[Faheem Mitha]

Package: python3-yaml
Version: 5.3.1-2
Severity: normal

Dear Maintainer,

I'm on Debian 10/buster.

I tried building pyyaml/python3-yaml on buster, and it failed. I then
upgraded libyaml to the version on unstable, namely 0.2.2-1, and it
built correctly, and runs on my current (small) script, though I have
hardly tested it. I didn't change anything else, so I conclude that
the build dependency on libyaml needs to be versioned to >=0.2.2-1.

A patch for this should be trivial, but I can submit one if you
want. I could even submit a pull request to
https://salsa.debian.org/python-team/modules/pyyaml, though I don't
currently have an account on salsa, and do not know anything about the
service.

Let me know. Thanks.

Regards, Faheem Mitha
