As a dwm fan, I feel obligated to point out that the philosophy there seems to be to create small programs with little overhead. I know little more of C than include stdio.h (which, being in my early 20's in the disco era, I always think of as studio h, as in Studio 54), but it's quite easy to figure out, and if not, there's a great tutorial on the Debian forums explaining it. Once it's been installed, if you want to say, change the bar from the top to the bottom, you would change one line and recompile, but it takes less than 10 seconds to do so.
The Debian forums tutorial is here.
However, I have to concede that on a multiuser system, with everyone using dwm, it would be a real pain. In such a case, something like spectrwm might be a better choice, plain text config file that can be easily adjusted for each user. I have another dated page about that one,
https://srobb.net/spectrwm.html
I suppose in FreeBSD, one could do make extract, have each user keep the work/dwm-6.2 file in their home directory, make their changes and install in $HOME/bin/, but it seems an unlikely scenario. Might just depend upon which user of the machine was more skilled at fighting.
However, I think, judging from the original post,that the OP wouldn't be sharing their FreeBSD workstation with anyone else. I could be wrong, of course. And the stock dwm install has some fairly sane defaults, even if they're not to my taste--for example, their default is alt+shift+enter which opens an st terminal. I prefer Mod4 (the Winders key) +r to open urxvt. You can at least change Mod1 to Mod4 during original port configuration.
BTW to the original poster. I don't know if anyone's mentioned this in either of the threads, but once you have your dwm port configured and installed and you're happy with it, you can always run
pkg create dwm
You don't need root privilege to do this and you can create it in your home directory if you like. Then, if an upgrade or an error messes up your configuration, you can reinstall the version that was working for you with
sudo pkg install dwm-whatever.txz
