Log Message:
Update to wmii-3.6, which now requires x11/dmenu and devel/libixp as external
dependencies.  Changes not explicitly listed, but the config file format
changed again. :-(  NOTES mentions: the semantics of WMII_MENU, WMII_9MENU and
WMII_TERM have changed. If you're using them in custom scripts you'll need to
change them to "eval $WMII_MENU" instead of just "$WMII_MENU"
