spamassassin does not list all required packages (3.4.1_9)

[Igor R.]

Hello!

As far as I can tell, spamassassin-3.4.1_9 does not list all required p5 
packages, which results in 3 error messages in /var/log/maillog upon 
starting the package:

Feb 25 11:16:08 <mail.err> tissa spamd[69929]: Can't locate URI/_idna.pm in @INC (you may need to install the URI::_idna module) (@INC contains: /usr/local/lib/perl5/site_perl /usr/local/lib/perl5/site_perl/mach/5.24 /usr/local/lib/perl5/5.24/mach /usr/local/lib/perl5/5.24) at /usr/local/lib/perl5/site_perl/IO/Socket/SSL/PublicSuffix.pm line 124.

With that, spamd starts and seemingly works (maybe not fully?).

Installing the three packages by hand got rid of the error messages.
p5-Net-IDN-Encode
p5-URI
p5-Net-LibIDN

The required packages as listed at 
https://www.freebsd.org/cgi/ports.cgi?query=spamassassin&stype=all&sektion=all
do not include these three:

spamassassin-3.4.1_9
     Highly efficient mail filter for identifying spam
     Long description : Changes
     Maintained by: ports at FreeBSD.org
     Also listed in: perl5

gnupg1-1.4.21_3, indexinfo-0.2.6, libnghttp2-1.19.0, 
p5-Digest-HMAC-1.03_1, p5-Encode-Detect-1.01_1, p5-HTML-Parser-3.72,

re2c-0.14.3, readline-6.3.8

I am not sure if these 3 packages are needed, but either they need to be 
addeed as required or (if they are not needed, which I doubt) the package 
needs to be patched to avoid the errors.

Best regards,

Igor
