Comment (by jrh@…):

 Replying to [comment:2 hum@…]:
 > Emacs.app is relocatable while /opt/local/bin/emacs is not, and you
 should not separate the Emacs binary from other data files, because the
 binary could not find them based on the relative paths.

 OK, so you're saying that Emacs.app is set up to search within its
 (relocatable) app bundle, and so the symlink fails because it's looking
 for stuff at {{{`dirname argv[0]`/libexec/}}} and {{{`dirname
 argv[0]`/../Resources/}}} (pardon the syntax abuse). That makes sense, and
 I suppose it means this bug is really a feature.

 The confusing part to me, though, is that the error messages look like
 {{{
