Copying the contents of /usr/lib/sasl2 into /var/spool/postfix/usr/
lib/sasl2/ results in errors such as:

May 26 20:52:50 mini postfix/trivial-rewrite[29635]: unable to
dlopen /usr/lib/sasl2/libsasldb.so.2: libdb-4.2.so: cannot open
shared object file: No such file or directory

Having a blank directory at /var/spool/postfix/usr/lib/sasl2/
resolves the issue as far as I can tell, so that's what I'm doing for
the time being. I'm not using cyrus-sasl so I don't care much about it.

I guess the question here is, how should this be resolved? It
appears that these errors would be generated on a default postfix
install on Debian or Ubuntu, since the cyrus-sasl stuff is a
dependency of the postfix .deb.

Do I need to file a Debian/Ubuntu bug report? Is it possible that
this is a misconfiguration on my end?

Thanks.
