Testnet Mining Question

[CajunCoin]

Hola!   I'm trying to mine funny money on the bitcoin testnet and having a problem getting my "bitcoins".  I sure hope somebody here can assist.  I can reward you with some conterfeit BTC for your time if we're successful.   

I've got a couple of bitcoind processes running (latest version 0.8.5) on a ubuntu VM.  I also downloaded the 'testnet-in-a-box' from github and followed the instructions with that to get things running.  I'm using cpuminer (minerd) to mine against it.  Things appear to be normal, here's some commands and their results which make me believe it's functioning normally. 

So, questions are, why aren't my coins confirmed and in my wallet? 
I see most have a category of 'immature' which I understand means their valid coins, but not truly valid until they are confirmed by peers on the network.  Isn't 10 confirmations enough?
I also never really told bitcoind where to put the coins, I figured it would just default to the default wallet.dat, but maybe I need to specify an address somewhere?

bitcoind getinfo
{
    "version" : 80500,
    "protocolversion" : 70001,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 31,
    "timeoffset" : 0,
    "connections" : 1,
    "proxy" : "",
    "difficulty" : 1.00000000,
    "testnet" : true,
    "keypoololdest" : 1386211650,
    "keypoolsize" : 6,
    "paytxfee" : 0.00000000,
    "errors" : ""
}
{
    "version" : 80500,
    "protocolversion" : 70001,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 31,
    "timeoffset" : 0,
    "connections" : 1,
    "proxy" : "",
    "difficulty" : 1.00000000,
    "testnet" : true,
    "keypoololdest" : 1338837868,
    "keypoolsize" : 6,
    "paytxfee" : 0.00000000,
    "errors" : ""
}

Here's the result of a bitcoind listtransactions command (just a snippet of the first of many similar ones):
        "account" : "",
        "address" : "n37fAnqNUcjJeKTG8YmHdqg9yjDtkxJSD2",
        "category" : "immature",
        "amount" : 50.00000000,
        "confirmations" : 10,
        "generated" : true,
        "blockhash" : "000000008061308fd286650e3ef34ee96838943ff96ae250a229f38ba69858d5",
        "blockindex" : 0,
        "blocktime" : 1386206816,
        "txid" : "e66fa4ae880ac2554e837e2e1496f5838c30b177be3d0e96e27db1778f7ac118",
        "time" : 1386206816,
        "timereceived" : 1386206816

Here's an excerpt from the bitcoind debug.log, it's basically just repeating this over and over for each block, but it looks happy - right?

Let me know if there's any other info you would find useful.  Thanks in advance!

Solved, now I'm mining like 50 blocks every 30 seconds.  Posting the fix in case anyone runs into this.  Compile bitcoind from source with the following 'fast-miner.patch'.  Enjoy!
