[Dnsmasq-discuss] Is updating dnsmasq.conf supposed to update dnsmasq.plist?

The .plist file is a Mac-only thing.  As such, it is not part of the "standard" dnsmasq distribution, but something that MacPorts adds.

For reference, the full contents of the file are:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
<plist version='1.0'>

This file is statically installed this way as part of the MacPorts dnsmasq package, and no, it isn't updated programatically.  This XML file is used by launchd(8) on OS X to know when and how to launch dnsmasq during boot.  (For other UNIX folks, launchd(8) is the replacement for init(8) and inetd(8)).  This is resulting in dnsmasq being invoked with a command line of:
	/opt/local/sbin/dnsmasq/dnsmasq -k -r /etc/resolv.conf
Since command-line options override the config file options in dnsmasq (as with most other utilities), your config file is ignored in preference of the .plist/command line option.  So it's MacPorts fault.  Why the MacPorts people decided that "-r /etc/resolv.conf" should be specified on the command line, I don't know, but it seems like a poor choice to me; you can just remove the lines corresponding to "-r" and "/etc/resolv.conf" and then it'll use your config file.  Maybe you should log a bug report with MacPorts.

-k is a reasonable command-line option for operating under launchd, which doesn't want processes to fork/exec.  (It will by default try to spawn another instance of the process if/when it dies.)  Don't remove that.

I finally went into the dnsmasq.plist file and saw that /etc/resolv.conf was listed. I changed that and everything was fine.

Apparently this is working fine as it does block the sites and doing a dig shows it is going to for any site. YET there is nothing in my plist to indicate that dnsmasq is supposed to read a separate hosts file. This makes me believe idnsmasq gets it's options from both dnsmasq.conf and dnsmasq.plist...
