Options:

--va build an alternate output bdb2a, use this to avoid overwriting a
|
||||
previous bdb2 library, since R0.3 the interfaces are not
|
||||
compatible due to the addition of transaction parameters to many
|
||||
calls. Note the impact on indicating the include, below.
|
||||
If you have not used bdb2 before, you need not use this argument.

--nsl add nsl rpc library to build (4.4 uses rpc for replication)

indicate where to look. Do not use --with... because we need

to find the file itself to extract all the DB defines.
