Please make sure that you have at least libxml2-2.7.6_2 in your ports tree
before even thinking about updating your ports tree. Older libxml2 uses
some knowledge of zlib internals that has been changed in this update which
is known to cause problem.
While the update sounds like a good idea (as does moving to symbol verisoning
for this library), I'm not yet convinced an MFC is a good idea given the
compatibility issues you describe. Perhaps you could clarify a bit the
failure mode: this affects only people who rebuild their ports using exactly
the same ports versions, but after having done an upgrade that includes this
update? It sounds like existing binaries will continue to work since they
will reference the old library version?
