Gah.

Right.

Their handling of the --with-libXXX value is completely non-standard.
They expect it to be pointed to the *build* directory of the library,
and not to a sysroot where it has been installed. I had the same issue
with libpcap, which is why I switched to using pkg-config.

Well, we already mess with the configure.in script: see my patch 0001
that changes the configure.in script to add support for using
pkg-config to check for libpcap's availability.

If you don't need libnet support as you're saying at the beginning of
this e-mail, then we can simply keep the --disable-libnet and that's it.
