There is a lchown manual page on 10.3, but running nm on
/usr/lib/lib*dylib and greping all headers in /usr/include shows no
lchown symbol.
The next rdiff-backup release may want to special case this.
Does 10.4 have lchown?
Yes.

What's 10.3, does that mean Mac OS X?
Yes.
How do people change the ownership of
symbolic links on your system without lchown?
I don't know.
I hoped for a second that it existed in the kernel and just not in a
standard userspace way. Then you could get to it through SYSCALL
(which Perl pushes through; Python probably does, too). But no go. I
don't see it in the kernel source for 10.3.2. I think it'd be here:
