spamassassin: spamd or spamassassin won't run - SpamAssassin.pm missing

Maintainer: @dangowrt
Environment: x86/64 22.03.2

Description:

spamassassin package does not contain SpamAssassin.pm so consequently various components do not function.
Discovered when trying to get Exim to use spamd.
Does not recognise AnyDBM dependency is installed when it is.
There are also no init.d scripts to start the service.

Can't locate Mail/SpamAssassin.pm in @INC (you may need to install the Mail::SpamAssassin module) (@INC contains: /usr/lib/perl5/5.28) at /usr/bin/spamd line 240.

AnyDBM perl package is installed, but sa_awl doesn't think so:

root@Router:~# perl -T /usr/bin/sa-awl 
No DBM package was successfully found or installed at /usr/lib/perl5/5.28/AnyDBM_File.pm line 17.

Raised it inside forum initially, but perhaps bug report is more suitable, apologies if thats not the case.

Thank you.

Start with the spamassassin package definition and the installed entry points /usr/bin/spamd, /usr/bin/sa-awl, /usr/bin/sa-compile, /usr/bin/sa-learn, and /usr/bin/sa-update. Verify that Mail/SpamAssassin.pm is packaged, AnyDBM_File can load its DBM backend, and service init scripts are provided; done means these commands run on the reported OpenWrt environment.
