 No, not for cross builds - On both FreeBSD 11 and OS X:
 
 $ printf '7.9.1\n7.9.0\n7.9.10\n7.10.1\n' | sort -t. -r -k1,1n -k2,2n -k3,3n
 7.9.0
 7.9.1
 7.9.10
 7.10.1
 
 This is (I think) because posix says that "If any modifier is attached to a
 field_start or to a field_end, no option shall apply to either."
 
 http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sort.html
 
 The NetBSD sort does this differently, but then again the man page doesn't
 mention posix.
 
 So to use modifiers, it needs to be
   sort -t. -k1,1nr -k2,2nr -k3,3nr
 but is there a reason not to use
   sort -t. -nr -k1,1 -k2,2 -k3,3
 ?
