cairo's buildlink3.mk and Makefile grew an lzo dependency. Packages
that depend on cairo now don't build against an older version because
lzo's buildlink3.mk is linked in, but lzo is not installed (because
previous versions of cairo didn't need it).
This leads to:
ERROR: lzo>=2.01 is not installed; can't buildlink files.
Please bump the ABI version in cairo's buildlink3.mk and do a
recursive revbump!
OK.
BTW: I think 'finddepends' is broken. If you looked, for example, for
graphics/gd, it would pick other packages which names begin with 'gd', like
graphics/gdk-pixbuf.
