OpenBSD 4.8 and later sport squid 2.7STABLE9 as a package and in the ports collection.
Binary Install Procedure:
pkg_add squid
Ports Collection Install Procedure:
cd /usr/ports/www/squid make install
Compiling
To build squid, no particular method should be needed. See SquidFaq/CompilingSquid for detailed instructions. If you plan to do development on squid, some caution is needed: apparently something in the mix of sources and libraries trips a bug in gcc when building parts of the test-suite with optimizations. Building with optimizations explicitly turned off will allow to compile fine. In other words you'll need to:
CFLAGS='-O0 -Wall -g' CXXFLAGS="$CFLAGS" ./test-builds.sh
Troubleshooting
NAT lookup failures
Due to deep changes in PF with OpenBSD 4.6 the ioctl() interface used by Squid to access NAT table entries was broken (intentionally removed?) for several OpenBSD releases. We are not quite certain when the ioctl() was fixed again but it apparently works as of OpenBSD 5.0.
