I definitely know lchown() is not on 10.3.9, since I stumbled onto this
while trying to build trunk there.  But the question is should we simply
disable the chown portion in port (maybe noop'ing proc chown in
portutil.tcl) for 10.3 or try and wrap all the privsep in a "not on 10.3"
conditional block(s)?  Disabling the chown means that other bits of the
privsep stuff will probably have issues as well, so maybe there's a way
to use the old method but ignore errors on symlinks?
