Hi Xin Li,

I am only now coming into this (and it seems that a significant number
of people have already reported on it). I can confirm that I've tried TB
and Enigmail from ports, and ever since around the time that 2.0.0.12
was brought in, I cannot get enigmail to work no matter what combination
of USE_GCC I have between mail/thunderbird and
mail/enigmail-thunderbird. I am using 8.0-CURRENT as of about four days
ago (just after sos@ imported the last of the sys/dev/ata fixes).

Since that time, I have managed to bring in some fixes to devel/glib20
that fix the shared-object module loading that used to make evolution
take 10 minutes to start up (seriously!). In addition, I sent some fixes
over to the seahorse crowd (and committed them to our seahorse port) to
fix breakage when using seahorse-agent w/ GnuPG. This allowed me to
finally use Evolution+GnuPG together.

I'll try the patch below on enigmail w/ TB to see if it fixes the
breakage in enigmail-tb for me now... but I may take a couple days time
getting reports back to you.
