First. Very sorry about the email address mess I made.

Fedora 2
I built DB-4.3.21.

../dist/configure
make
make install

No flags.
No errors on the build or install.


I installed bogofilter from the bogofilter-0.93.2-1.i586.rpm.
No errors here either.
rpm -Uvh bogofilter-0.93.2-1.i586.rpm

I have the DB-4.3.21 config.log gziped.
Just not sure where to ftp it.
So I put a copy here,
http://files.attitudejim.com/jims_berkeley_4.3.21_config_log.gz

Thank you for your  time.
