+BerkeleyDB is required for the wallet functionality.
+Historically Bitcoin was first deployed with now deprecated BerkeleyDB-4.8, which has resulted in the need to upkeep the compatibility with those ancient deployments to this day. BerkeleyDB-4.8 is not compatible with more modern BerkeleyDB-5.1 and BerkeleyDB-5.3. Peercoin has inherited this in the first versions and this is why Peercoin is still officially shipped out with BerkeleyDB-4.8.
+However if you running a new wallet on a new installation there is absolutely no need to run old and deprecated BerkeleyDB-4.8. Just use the one avaliable in the repository of your distribution.
 
 **For Ubuntu only:** db4.8 packages are available [here](https://launchpad.net/~bitcoin/+archive/bitcoin).

 Mining is also possible in disable-wallet mode, but only using the `getblocktemplate` RPC
 call not `getwork`.
