Re: Deprecated Perl support from Maxmind

I'm the author of IP:Geolocation::MMDB, which is an API-compatible 
replacement for MaxMind::DB::Reader. Packages are in Fedora, in SUSE's 
devel:languages:perl repository and hopefully soon in Debian.

I created the file MaxMind/DB/Reader.pm in my @INC path, which creates a 
subclass named MaxMind::DB::Reader. I've been using this work around for 
months with SpamAssassin:

     use IP::Geolocation::MMDB;
     @MaxMind::DB::Reader::ISA = qw(IP::Geolocation::MMDB);
     1;

Patching GeoDB.pm is also trivial:

     --- a/lib/Mail/SpamAssassin/GeoDB.pm
     +++ b/lib/Mail/SpamAssassin/GeoDB.pm

     +    @MaxMind::DB::Reader::ISA = qw(IP::Geolocation::MMDB);
       } or do {
          my $err = $@;

SpamAssassin's test suite requires more work. IP:Geolocation::MMDB works 
with Perl 5.16 and above. I'm struggling with SpamAssassin's tests on 
Windows though. IP::Geolocation::MMDB is an XS module and most Perl 
releases for Windows before 5.34 have issues with linker library paths 
and libraries that are linked in the wrong order. I am also going to 
release a new version of Alien::libmaxminddb, which doesn't depend on 
Alien::Build.
