Caught the error above running 'make check' to install Glitter, a GTK+/Gnome news reader.
After some to-ing and fro-ing, I searched and found that this error referred to a missing libdb1.so "file" which in fact is a link file pointing to /usr/lib/libdb-1.##.so. This file is installed with Berkeley Database. What I found was that I had the "DB1" package installed, but not the "DB1-devel" package.
As I run SUSE 10.0, I ran my trusty dusty YaST2 Software Manager, installed the "devel" file (and the other DB packages - DB4, DB41, etc... for good measure). I made clean with "make clean" reran "configure", and "make check". Both worked smoothly. After that, "make install" installed Glitter to my system smooth as ever.
Hope this helps you if you ran into the same problem. Leave a note in the comments section if this helped your particular problem. Note what you were doing (e.g. installing program X) in case anyone else doing the same thing runs into this problem. Thx!
