I can now report that there will be problems if you rebuild just the  
perl port. I used portmaster to perform this task. Then I discovered  
that (at least some of the) libraries built against non-threaded Perl  
refuse to be loaded with threaded Perl. A rather typical error message  
you'll see is 'Undefined symbol"PL_sv_undef"'.

In order to get amavisd-new running again, I rebuilt the following  
ports using portmaster:

devel/p5-Time-HiRes
sysutils/p5-Unix-Syslog
security/p5-Crypt-OpenSSL-RSA
www/p5-HTML-Parser
converters/p5-Convert-UUlib
textproc/p5-YAML-Tiny
devel/p5-ExtUtils-CBuilder
devel/p5-ExtUtils-ParseXS
devel/p5-ExtUtils-Install
devel/p5-version
devel/p5-Module-Build
converters/p5-Encode-Detect
net/p5-IO-Socket-INET6
net/p5-Socket6

I now have amavisd-new running again, but it is possible that I'll  
discover more (non-amavisd-related) ports that need rebuilding.
