 I asked for @1.52.0, a perfectly reasonable thing to do, but port instead
 installs 1.53.0.
 This is wrong.
 Port should install the version I asked for, or if it can't or won't, then
 it should complain and exit nonzero. Until such time as port would be so
 kind as to actually install an asked-for old version, it could help by
 printing out the svn command I would need to use to get the old version,
 or better yet, a shell command that gets it and puts it in the right
 place.
