Hopefully these 3 commits will do it(code-fixes.patch):

Patch 1 will correct the error you have point out!
On OpenWRT the lock utility doesn't allow to append the pid of the
currently running script to the LOCKFILE that's why I've simply
deleted that line(patch 2).
I've also reordered the permissions line to be added after the line
that will lock the file specified by the LOCKFILE variable(patch 3).

and two other patches:
While installing shorewall-init using the DESTDIR variable on debian,
'mkdir' would complain if the directory ${DESTDIR}/${etc}/default
already exist; corrected using 'mkdir -p ...'(patch 4).
The last patch will correct a typo in the blacklisting_support
article.
