Public bug reported:

Note: currently squid3 fails due to libecap3-dev dependency, this is
easily fixed by going back to libecap2-dev (only squid 3.5+ will build
with libecap3-dev [1]).

After libecap2-dev dependency fix, squid then fails due to "logical-not-
parentheses".

Fixing that, it then fails due to mismatching headers between linux-
libc-dev_4.2.0-10.11 and libc6-dev_2.21-0ubuntu4.

<snip>

Tried to ignore "#include linux/netfilter.h" in src/ip/Intercept.cc:99
to no avail as build fails later on due to missing "SO_ORIGINAL_DST" in
Intercept.cc. Removing arpa and netinet header inclusions also lead to
eventual build failures due to missing symbols.

So far I have found no way to have squid linking solely to either the
kernel or libc without disabling netfilter altogether.
