Comment (by mfeiri@…):

 When talking about binary compatibility you are thinking of something like
 rev bumping all dependents, e.g. as in
 http://trac.macports.org/changeset/69520 for openssl 0.9.8->1.0.0, right?
 AFAIK the new 'rev-upgrade' action in MacPorts 2.1 should handle this
 automatically. It  "... checks for and rebuilds ports that may have become
 incorrectly linked when a dependency was upgraded to a new, binary-
 incompatible version. This runs automatically after upgrades and installs
 ...", see http://trac.macports.org/browser/trunk/base/NEWS and
 https://trac.macports.org/wiki/SummerOfCode2011#rev-upgrade

 There is a small chance that some ports are not API compatible with
 version 3 of libarchive. A quick grep through the dports hierarchy reveals
 just 5 ports (hydrogen, elftoolchain, gvfs, epic5, ark) that actually
 depend on libarchive. Verifying that these 5 ports still build/work
 properly after the patch in #38164 is applied should be all we need.
