From: Ilya Tumaykin <itumaykin@xxxxxxxxx>
ulogd has automagic deps for several output plugins right now, namely dbi,
pcap and sqlite3. These plugins are built if the appropriate libs are present
on user's system. While this situation is fine with binary distros it is not OK
on source-based ones such as Gentoo.
The problem arises when such a program links against libs without user's
request and libs are later removed from system which leaves program in a
broken state.
This patch is modifying configure.ac which we apply in our package and which
fixes mentioned issue. It adds 3 new configure options: --
without-{dbi,pcap.sqlite}. I would like to emphasize that this patch doesn't
change default behaviour of configure script at all, so all other distros won't
suffer. We simply add options to explicitly disable any attempts to try and
detect libs for automagic deps, which is enough to avoid unnecessary linkage.
