Well, I found it on my system. The short answer is that it's provided
by the 'aout-libs' package, which is presumably on your CD, as mine
apparently came from the Red Hat 6.0 upgrade I did. Mine is version 1.4:
aout-libs-1.4-9. 

I found this with rpm. If anyone wants encouragement with trying to
remember the multitude of silly rpm options, and a reason why they're
occasionally helpful, then here's what you can do if you do remember 
them! (I'm feeling quite proud now!) If you don't use it, or you use
Debian or Slackware, feel free to hit delete here. I added some 
comments, tabbed in. If everyone knows these already, sorry. I have 
only just got the hang of them well enough to find them really useful, 
so I thought I'd share :)

[hobbit at aloss ~/CVS/gnome-libs]$ locate libdb.so.1
/usr/i486-linuxaout/lib/libdb.so.1
/usr/i486-linuxaout/lib/libdb.so.1.85.1

	locate is massively useful. You don't need the entire name
    file: but the shorter the part of the filename you give, the more
    chance you have of throwing up entirely unrelated files. 

	Conclusion from that: it definitely exists :) So to find out 
    which package the file came from: 

[hobbit at aloss ~/CVS/gnome-libs]$ rpm -qf /usr/i486-linuxaout/lib/libdb.so.1

aout-libs-1.4-9

	rpm -qf: query file and tell me which package it came from.
	I've never heard of the answer, so find out more:
	
[hobbit at aloss ~/CVS/gnome-libs]$ rpm -qi aout-libs

Summary     : Compability libraries for old a.out applications
Description :
Old Linux systems used a format for programs and shared libraries called
a.out while newer ones use the ELF format. In order to run old a.out
format programs, you need the a.out format libraries which this package
provide. With it, you are to run most a.out format packages for text,
X, and SVGAlib modes.


	rpm -qi: query for information about a package
	(Please ignore the install date on my machine: I had a slight
    accident with the clock back when I upgraded from Red Hat 5.2 to
    Red Hat 6.0!) Hmm. So that's what it is. Wonder what other files 
    it provides? Oh, wait, the output of this command is usually horribly 
    long so let's cut it down a bit:

[hobbit at aloss ~/CVS/gnome-libs]$ rpm -ql aout-libs | grep libdb
/usr/i486-linuxaout/lib/libdb.so.1
/usr/i486-linuxaout/lib/libdb.so.1.85.1

	rpm -ql: query list of files a package provides. I know from
    experience it's usually horrendously long, but I was just idly
    curious what else it provided, so I added the "| grep libdb" in
    there to cut down on the number of files I'd get. I tried again, 
    without the piping through grep, and got 33 files, so there's quite 
    a few :)

I hope that wasn't all desperately boring.
