Unfortunately this is correct. The sh4 architecture is only an unofficial port of Debian, a secondary architecture. It seems it can't keep up with package changes. Architectures transitioned to ICU 72.1 (version is 72.1-3 to be exact) and that's also built for sh4 [1]. Reason why boost1.74 can't pick that up seems to be numpy; build status [2] shows it needs build dependency on python3-numpy (>= 1:1.21.5-2) and libicu-dev (>= 72). The latter is OK, but stuck on the former [3]. To cut it short, digging down on the mentioned page through python3-matplotlib I see the culprit build dependency is python-greenlet [4] which fails to build on sh4. It seems it was never built there as the error is [5]: src/greenlet/greenlet.c:376:6: error: #error "greenlet needs to be ported to this platform, or taught how to detect your compiler properly."

That's because ICU was transitioned to version 72.1 as noted above which also happened and available on sh4 [6]. > I'm not really sure how to proceed. You may locally hack the build of boost1.74 not to require Python (and drop its related binary packages). Of course, best would be to port python-greenlet to sh4 or just fix its build - can you give a helping hand to its upstream? At least this is what I see without access to any sh4 machine. As we know each other, I may check it for you if I can access that machine. But I think you are much more skilled in these things.
