Using the latest official 0.8.1 for Linux. bitcoind stopped downloading at block 182687 and I get a warning to upgrade:
64 # ./bitcoind getinfo
{
    "version" : 80100,
    "protocolversion" : 70001,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 182687,
    "connections" : 8,
    "proxy" : "",
    "difficulty" : 1591074.96184731,
    "testnet" : false,
    "keypoololdest" : 1367805478,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "errors" : "Warning: Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade."
}

I found there is a similar problem for the Ubuntu PPA version, related to BDB, but I doubt this is the same thing. I don't see BDB in the dynamic dependencies - it must be statically linked:
64 # ldd bitcoind
