/usr/ports/www/oops port does not compile with Berkeley DB4 library due to a bug in configure script and a wrong header location in sources.
It is also build-dependant on gawk, which is not mentioned anywhere (this is a bug in autoconf213, unconditional setting of AWK=gawk on 40-th line).
Another problem with this port is described in ports/40593.
Fix: Original patches available at http://www.mokr.ru/files/patch-oops-220.127.116.1120519.tgz
How-To-Repeat: run 'make' and select DB4 storage type
So I can see feedback.
