Right, that's what I said :-) Either method is "more hassle" than
just patching the configure script when on the darwin_8 platform.

Yes, I suppose my original question was why the configure script
for xfce4-settings couldn't do that without me patching it first...

Right you are. I just thought it would say "too old" rather than:
"checking for optional package xcursor >= 1.1.0... not found"

But I won't bother to find out why, since my XFree86 version of
xcursor is 1.0.0 anyway and it's also optional for this package.
