Wait a minute... what do you mean with "least amount of problems"? If you mean easy installation, then PODBot mm might not be the ideal choice... yet.
As biohazerd87 correctly stated, it requires MetaMod to run. You would have to d/l MetaMod and set it up manally, and then you would have to make it load PODBot mm manually... it's not all that hard, but I'm saying that as a rather experienced comp user. For a newb, it may all appear very confusing.
If you want to try PB 2.6mm, I suggest you download THIS:

As the file name suggests, it's a package that already contains the bot itself PLUS metamod, and the best of it is: It's all pre-configured so you don't have to fiddle around very much. Here's the thread with further links and instructions on where to unzip the file:
