解决方案：
#perl -MCPAN -e shell

#cd /usr/ports/mail/p5-Mail-SpamAssassin
#make clean (Don’t forget always make clean after getting error)
#make install
Some package maybe just already installs with older version, just make deinstall, make clean then, start again.
sa-update now places state files in /var/db/spamassassin and not
/var/lib/spamassassin. This is to be consistant with Freebsd file
directory conventions.
If you run sa-compile, you will notice that files are in
/var/db/spamassassin/compiled// instead of
/var/db/spamassassin/compiled/.
No attempts have been made to move old versions over. You must recompile.
If you are running with spamd, you must add the following to rc.conf:
spamd_enable=”YES”
Security Note: If you did NOT deselected AS_ROOT, spamd will be runn ing
as root. To change this, also add this to rc.conf:
spamd_flags=”-u spamd -H /var/spool/spamd”
