Anyway the upshot was:
debian:~# ls -l /lib/libdb*
-rw-r--r-- 1 root root 233488 Apr 18 2002 /lib/libdb.so.3
lrwxrwxrwx 1 root root 15 Feb 14 21:00 /lib/libdb2.so.2
-> libdb2.so.2.7.7
-rw-r--r-- 1 root root 262812 Apr 18 2002
/lib/libdb2.so.2.7.7
debian:~# apache
apache: error while loading shared libraries: libdb.so.2: cannot open
shared object file: No such file or directory
so it's back to:
debian:/lib# ln -s libdb.so.3 libdb.so.2
debian:/lib# apache
