Hi Mike,

I have trouble to reproduce the problem here:

# USE="python_single_target_python3_9 -python_single_target_python3_8" nice ebuild $(portageq get_repo_path / gentoo)/dev-libs/volume_key/volume_key-0.3.12-r2.ebuild clean install
...
# find /var/tmp/portage/dev-libs/volume_key-0.3.12-r2/image/ -type d -name "python*"
/var/tmp/portage/dev-libs/volume_key-0.3.12-r2/image/usr/lib/python3.9


# USE="-python_single_target_python3_9 python_single_target_python3_8" nice ebuild $(portageq get_repo_path / gentoo)/dev-libs/volume_key/volume_key-0.3.12-r2.ebuild clean install
...
# find /var/tmp/portage/dev-libs/volume_key-0.3.12-r2/image/ -type d -name "python*"/var/tmp/portage/dev-libs/volume_key-0.3.12-r2/image/usr/lib/python3.8


can you give me any hints how to reproduce your issue?

from the build.log:
checking whether to use Python 3 bindings... testing
checking for python3.6... /usr/bin/python3.6
checking whether /usr/bin/python3.6 version is >= 3.5... yes

from the configure.ac:
AC_MSG_CHECKING([whether to use Python 3 bindings])
...
if test "x$use_python3" = xno; then
    AC_MSG_RESULT([no])    
else
    AC_MSG_RESULT([testing])
    # Try to find Python 3 interpreter:
    AC_PATH_PROGS([PYTHON3], [python3.6 python3.5 python3 python], [no])

i'm guessing you don't have python3.6 or python3.5 on your system which is why you aren't seeing the problem.

Exactly! Thanks for giving me that hint. Fix incoming.
