nudge.  Since it doesn't cause an issue and /var/run cleans itself, I would still vote on leaving as-is. Also, I found that this path is also coded into source/libike/libike.h, so I would have to patch that if you decided otherwise.
PR open for quite a while, would like to get this wrapped up.
side comment: is there an alternate/cleaner strategy to having these plist blobs in the formula?   Something like inreplace/patch the plist that comes with the source and `cp "source.plist" plist_path`? after `make install` or in post_install?
