Python limited API works on linux, but you do not link against the .so on linux

You will have missed that libpython3.so is a symlink to libpython3.11.so.10.

Beware that this idea has come up in the past and was r

A few years ago the spam count was greater than a 1,000 a month.
I have been using spambayes for a very long time, 20 years I guess at this
