i was going to suggest doing ldd on the binaries or a grep on the
Makefile but the latter returns a surprisingly low number
of matches.


> grep lxo */*/Makefile*
rescue/rescue/Makefile:CRUNCH_LIBS+= -lcrypt -ledit -ljail -lkvm -ll
-ltermcapw -lutil -lxo
tools/bsdbox/Makefile:CRUNCH_SHLIBS+= -lc -lutil -lcrypt -lxo -lgpio
perhaps
