What the best way to add the Webalizer program to a MC store? What problems have some of you seen trying to use this program with MC?

Since MC customers don't have command line access or FTP access, Webalizer isn't going to work for you.

On the bright side though, Urchin 5 is a very similar program and is free with any of our packages, or you can upgrade to Urchin 6 for an additional fee.

Not to sound like a salesman, but the folks around the forums at least seem to really dig U6, and if I'm not mistaken, there's some kind of free trial for it.

Give tech support a call if you'd like to enable either of these services.
