Building pkgsrc/textproc/libcroco (after doing make clean clean-depends) 
is failing with:

It does have dbus-glib buildlinked but not its includes of dbus, expat or 
glib2.

My work/.*_makevars.mk files have:
BUILDLINK_PREFIX.dbus-glib=   /usr/pkg
_BLNK_PKG_DBDIR.dbus-glib=    /var/db/pkg/dbus-glib-0.61
(but not "dbus")

It is after my bed time, so I will have to look at this later :)
