pkg_info may list 750+ ports, but that includes both build depends
(which really need to be re-built) and run-time depends which just
link to the .so and don't. Install sysutils/bsdadminscripts and use
'pkg_libchk -o' to get a list of the ports that REALLY need
rebuilding. It's probably only a dozen or less as libxcb is typically
only used by linking to the .so.
