Bug#1075851: mayavi2: FTBFS on ppc64el and riscv64

Source: mayavi2
Version: 4.8.1-5
Severity: serious
Tags: ftbfs
X-Debbugs-Cc: [email protected], [email protected]

Hi Maintainer

mayavi2 FTBFS on ppc64el [1] and riscv64 [2], where it built
previously.   I've copied what I hope
is the relevant part of the log below.

This is blocking the transition to Python 3.12 as default.

Regards
Graham
