For 5.8-5.9 something like "pkg_add -z squid-3.5.99" is likely to work. There is specific handling for this in -current, see pkg_add(1): There is also an ambiguity related to ports with multiple branches. For instance `pkg_add python' is ambiguous, as there are several versions of python in the ports tree. So is `pkg_add postfix'. The special form `pkgname%branch' can be used to restrict matches to a branch matching the pkgpath(7).
