The log just shows
configure:12079: result: -ldb

I searched with synaptic, and I could not find any 4.x versions
available from the repositories - only 5.1 and 5.3.

Currently it's hard to see how I do.  Configure didn't seem to find a
4.x version unless I missed something in the log.  I did have 4.8
installed prior to upgrading from 12.04 to 12.10.

Here's the beginning of the output of sudo ldd /usr/bin/xastir

A reference to libdb5.1 is there, hmm.
