Somewhat. The situation is like this:
iproute has plugins that are loaded at runtime with dlopen. Some of them
need libxtables. So unless these plugins are actually used libxtables is
not needed. So libxtables a optional _runtime_ dependency but to build a
working plugin its a required _buildtime_ dependency.
The current code is rather broken. It has some imported iptables headers
(from version 1.6.0), but those are useless because xtables-version.h is
missing...
