library(bdb) is built on top of Berkeley DB. It is an
optional component of SICStus and nothing, except library(bdb),
will be affected if Berkeley DB is not installed on the machine.
Berkeley DB can be downloaded from:
http://www.oracle.com/database/berkeley-db/
library(bdb) is built using version 4.8.24 or some later version
of 4.8.x. It may be possible to recompile it to work with other versions
as well.
