Unfortunately it looks like it wasn't quite enough. All, or nearly all, your
animals that ran since still seem to be failing in the same spot...

checking Python.h usability... no
checking Python.h presence... no
checking for Python.h... no
configure: error: header file <Python.h> is required for Python


For that machine (and the other debian based ones) the relevant package likely
is python3-dev.

For the Red Hat and Suse ones, it's likely python3-devel.


I've wondered before if it's worth maintaining a list of packages for
dependencies for at least the more popular distros. It's annoying to have to
figure it out everytime one needs to test something.


FWIW, here's the recipe I just used to verify the packages necessary for
Python.h to be found:

$ podman run --rm -it opensuse/leap
# zypper install -y python3
# ls -l $(python3 -c "import sysconfig; print(sysconfig.get_config_var('INCLUDEPY'))")/Python.h
<file not found>
# zypper install -y python3-devel
# ls -l $(python3 -c "import sysconfig; print(sysconfig.get_config_var('INCLUDEPY'))")/Python.h
-rw-r--r-- 1 root root 3221 Jan  4 14:04 /usr/include/python3.6m/Python.h

(Wow, zypper repos are expensive to refresh. And I thought dnf was slow doing
so, compared to apt.)

Greetings,

Andres Freund
