Easiest fix, I believe, is to drop the flag and upgrade to 0.8.
Upstream has dropped BDB in favor of leveldb for the blockchain and
only use BDB for the wallet (which is tiny). This can go on the TODO
list for the next upgrade.

>From the release notes: "LevelDB, a fast, open-source, non-relational
database from Google, is now used to store transaction and block
indices. LevelDB works much better on machines with slow I/O and is
faster in general. Berkeley DB is now only used for the wallet.dat
file (public and private wallet keys and transactions relevant to
you)."
