It‘s a reasonable way forward, given the limitations you described (you’re removing /var/run, which shouldn’t be removed and the port maintainer not willing to add code to compensate for this). This would fix it for you for your specific needs in a reliable way, you would never have to patch the port again and also won’t use other people‘s time to find a general solution to your very specific problem. It’s a sustainable quick fix to your problem at hand. You can always come up with something grand later, but this would actually work right away.
