You should not explicitly enable any plugins unless you have a very specific
reason for it. The configure script should only disable plugins which cannot
be build because of missing dependencies, so, usually, you will have to check
for those if a plugin does not get build automatically.

... in this case, you're missing the iptables headers (libiptc).

Florian, I think, we should remove all the HAVE_FOO_H checks from plugins that
require specific headers. This should provide more reasonable error messages
to the users when a build fails.

This is a common error on a lot of (mostly 64bit) architectures. You need a
version of the library (libnetlink in this case) which has been compiled with
-fPIC. See Debian bugs #358637 ([1]), #419684 ([2]) and #430933 ([3]) for more
details about this issue.

You'll have to nag your distributor to provide a suitable version of the
library (netlink and nut probably come up with the same issue) or compile it
yourself.

Florian, I think this should be added to the FAQ as it appears quite
frequently. I will write an answer for it later and ping you on IRC.

HTH,
Sebastian
