Have you installed python3-dnspython ?

Slackware is a bit unrepresented on this list, there is/was a person 
that used (something to do with the Ohio state police retirement fund
if I recall correctly) Samba on Slackware.

We do have a wiki page for the packages required to build Samba:
https://wiki.samba.org/index.php/Package_Dependencies_Required_to_Build_Samba

Unfortunately it doesn't mention Slackware, but it should provide
pointers.

Never tried building Samba on Slackware, but all versions should build,
as long as all the required files are installed.
