Yesterday I spend a few hours trying to install Webalizer on Mac OS X 10.6 (Show Leopard), with no luck. After some browsing, I found instructions how to migrate MacPorts, but I got stuck with Error: Checksum (md5) mismatch for jpegsrc.v7.tar.gz. Looks like it is fixed, and Webalizer installed with no problems today with just:

sudo port install webalizer
