problem is that on Arch /usr/bin/python points to python3 rather than

Can you show what exactly fails, maybe it is easy to fix/adding support
for python3?!
I get linker errors. Just an example:
table_python.c:(.text.startup+0x7f): undefined reference to
`Py_InitModule'
Py_InitModule was removed for the python3 API [0].
This means building opensmtpd-extras with python enabled fails as
it expects python2. I have attached a patch that fixes the build
script to
explicitly check for `python2` rather than the generic `python` to
avoid any
ambiguities.
Sorry, but I think this is not enough and breaks other distributions,
which do not link /usr/bin/python to python3 by default.
You're right, the change was rather short-sighted. Sorry.
I guess more sophisticated conditional checks/tests for python version
are required here.

Joerg
