I think the package is called pyxml? emerge -1 pyxml, then revdep-rebuild.

Also, OP should be aware of the USE flag changes for
ucs2/wide-unicode. A snippet from dev-lang/python's ChangeLog (also
see referred bug report):

  06 Dec 2009; Arfrever Frehtes Taifersar Arahesis <arfrever@gentoo.org>
  python-2.4.6.ebuild, python-2.5.4-r3.ebuild, python-2.6.2-r1.ebuild,
  python-2.6.2-r2.ebuild, python-2.6.3.ebuild, python-2.6.4.ebuild,
  python-3.1.1-r1.ebuild, metadata.xml:
  Remove "ucs2" USE flag and add "wide-unicode" USE flag (bug #293135).
