What do you have to say to that, CoinHunter?
That is one reason that the BSD OSs still use the 1.8 version of BDB, as that was a pure bsd licenced version.
However, did you actually read the sleepycat license for the 4.7 versions or are you solely going by the bitcoin developers quick one line summary? The license itself only says that source code must be available by being included or being made available for no more then distribution costs. No where does it say what specific redistribution terms must be on that source code itself, just that they have to be 'reasonable' for redistributions. They are not using the OSI definitions here that you are. No where do they say you have to allow reuse in other projects.
