It=E2=80=98s a reasonable way forward, given the limitations you described (= you=E2=80=99re removing /var/run, which shouldn=E2=80=99t 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 h= ave to patch the port again and also won=E2=80=99t use other people=E2=80=98= s time to find a general solution to your very specific problem. It=E2=80=99= s a sustainable quick fix to your problem at hand. You can always come up wi= th something grand later, but this would actually work right away. Cheers
