To be consistent here if should be berkleydb=4.1 not 41+ your are setting the

Please also add a WARNING+ about the WITH_*_VER usage saying that Users might
consider switching to default version.

I'm expecting to review all of that, imho let's start with the 3 you have
already written, others will come, do not forgot to CC the different maintainers
about the it (acm@ for firebird, mandree@ for berkeleydb).
