ImportError: cannot import name 'Union' from '_ctypes' (unknown location)

[Larz60+]

I have never had to compile, use pyenv see: https://python-forum.io/Thread-pyenv-Sim...ight=pyenv
If I do normal install, Ialways use install packages from python.org

python 2.7 is kaput, reached end of life January 1 of this year.
Again if for some reason you must use this version, it's a snap to install with pyenv
see: Pyenv - simple python version management

sorry Larz but I don't understand

first I have a configure error (solved) and a compiler error (still to solve)

root@crbosrv2:/presidio_sun/SUNFREEWARE/python/Python-3.8.5$ ./configure
checking build system type... sparc-sun-solaris2.10
checking host system type... sparc-sun-solaris2.10
checking for python3.8... python3.8
....
checking whether float word ordering is bigendian... unknown
configure: error:
Unknown float word ordering. You need to manually preset
ax_cv_c_float_words_bigendian=no (or yes) according to your system.

This first problem has been solved with:

find /usr -name ggrep
/usr/sfw/bin/ggrep
PATH=$PATH:/usr/sfw/bin
export PATH
