gnome-keyring-2.26.3 fails to build with libxml2-2.7.7

gnome-keyring won't build. This is the part of the log that seemed relevant, but I've attached the whole thing since I don't know enough to be sure.

What is the output of the following?

port installed zlib libxml2

This may be another victim of #24067.

Replying to macsforever2000@…:

I've actually switched back to a previous version of zlib to get past an earlier error with gnome-vfs related to the bug you mention.

macbook:~ logan$ port installed zlib libxml2
The following ports are currently installed:
  libxml2 @2.7.7_0 (active)
  zlib @1.2.3_4 (active)
  zlib @1.2.4_0

[macsforever2000@…]

Then you likely will need to rebuild libxml2.

sudo port -f uninstall libxml2
sudo port install libxml2

That fixed it. Thanks and sorry for filing the unnecessary bug.
