HOME/ext/x86_64-suse-linux-gnu/debug/bin/python3: error while loading shared
libraries: libpython3.12d.so.1.0: cannot open shared object file: No such
file or directory

 What is HOME/ext/x86_64-suse-linux-gnu/debug/bin/python3 and why is
HOME/src/mono.git/acceptance-tests trying to use it?

         linux-vdso.so.1 (0x00007ffd18e9a000)
         libpython3.12d.so.1.0 => HOME/ext/x86_64-suse-linux-gnu/debug/lib64/libpython3.12d.so.1.0 (0x00007f9c5d374000)
         libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f9c5d350000)
         libdl.so.2 => /lib64/libdl.so.2 (0x00007f9c5d349000)
         libutil.so.1 => /lib64/libutil.so.1 (0x00007f9c5d345000)

         /lib64/ld-linux-x86-64.so.2 (0x00007f9c5dab4000)

 So HOME/ext/x86_64-suse-linux-gnu/debug/bin/python3 does find
HOME/ext/x86_64-suse-linux-gnu/debug/lib64/libpython3.12d.so.1.0 if you
invoke it from the shell (to confirm that, try actually invoking it
instead of running ldd on it), but not when it's called from whatever
make is doing in the acceptance-tests directory.
 So it might be because it's in a different directory ("HOME/ext/..." is
a relative path. That will not work in a different directory. Also
"HOME" is a strange choice for a directory name. Did you mean $HOME?) or
because the acceptance tests set up their own environment.
 I'd test the first idea first. Cd into
HOME/src/mono.git/acceptance-tests and try to invoke
HOME/ext/x86_64-suse-linux-gnu/debug/bin/python3 there.

The CORE problem is that python3 works well in *my* environment but the
installation is done as root and root does not use *my* environment.
the mono build search for a working python3 and find *my*
 > HOME/ext/x86_64-suse-linux-gnu/debug/bin/python3
The build is fine but after switch to root for installation
 > sudo make install
the root user call *my* python3 and fail.
