[ryandesign (Ryan Carsten Schmidt)]

$ port livecheck libxml2
libxml2 seems to have been updated (port version: 2.8.0, new version: 2.9.0)

[jmroot (Joshua Root)]

py-libxml2 is built from the same sources and should be updated as well.

Replying to egall@…:

Local-Admins-MacBook-Pro:my_dotfiles ericgallager$ port dependents libxml2 | wc -l
     126

That only shows you the dependents that are currently installed.

% port file all | sort -u | xargs grep -El ':(libxml2|py.+-libxml2)' | wc -l
     242

Local-Admins-MacBook-Pro:my_dotfiles ericgallager$ port rdependents libxml2 | wc -l
    1320

...looks like a lot of stuff is going to need to be revbumped...

Dependencies of dependencies do not need revbumps due to library updates. If a file links against a library, its port should have a direct dependency on the library’s port (libtool nonsense aside).

In any case, nothing will have to be revbumped. As far as I can tell from inspecting the source, the library name is not changing.

libxml 2.9.0 doesn't build on OS X, see ​https://bugzilla.gnome.org/show_bug.cgi?id=684024 for the bug report and a patch.
