My system is very old and the PERL installation is a mix of CPAN and dnf.

Given the lack of a cpan uninstall command, I have now deleted every file that 
looks like Zlib.
That has stopped the original error but now amavisd fails at line 250: 
presumably because it can't find Zlib.

I have just uninstalled amavisd and reinstalled (using dnf).
Now I get:

fetch_modules: error loading required module Compress/Zlib.pm:
   Can't locate Compress/Raw/Zlib.pm in @INC (you may need to install the 
Compress::Raw::Zlib module) (@INC contains: /usr/local/lib64/perl5 
/usr/local/share/perl5 /usr/lib64/perl5/vendor_perl 
/usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at 
/usr/share/perl5/Compress/Zlib.pm line 11.
   BEGIN failed--compilation aborted at /usr/share/perl5/Compress/Zlib.pm line 11.
   Compilation failed in require at /usr/sbin/amavisd line 210.

If I try to install Compress:Raw::Zlib, I get "already installed".
