I guess the references to my previous experience on FC2 do cloud things
a bit.

Why would I use a source rpm from FC2? :)
It's Centos/RHEL 4's cyrus-sasl rpm. Specifically, the cyrus-sasl-sql
rpm. It appears all other code seem to work except for the sql plugin. I
am not sure if that is due to configuration error, which seems unlikely
since i copied the configuration for smtpd.conf from the FC2/Opteron
box, or due to threading /sasl initialization issues.

Nope. All I could find from searching on the '_dl_sysinfo_int80 ()'
string was something about threading or hyper-threading being enabled
causing crashes...does Pentium 4 2.8 Ghz cpus have hyper-threading?

Boo.

Wish I did have one...otherwise I would have just filed a bug report.
Anyway, I recompiled the cyrus-sasl source rpm after enabling another
plugin that I could make use of and now things are working for me...the
the rebuilt sql plugin still crashes but the other plugin allows me to
make use of the mysql tables I have without doing pam_mysql.
I wonder what is it that is causing the crashes...the logs tell me that
postfix initiated sasl initialization and then it crashes with no other
information...but I guess I can drop it now...
