Comment(by ryandesign at macports.org):

 /opt should not be a symlink. But it seems that CiscoVPN versions before
 4.9 did appropriate /opt and make it a symlink pointing to /private/opt.
 We had a FAQ entry about this but it was removed in 2006 because it was
 thought to no longer be relevant for current versions of the Cisco
 software.

 Apologies for the unprofessional language in this FAQ entry; it's old
 documentation that has already been deleted from the current FAQ, but I
 bring it up because it seems relevant to this ticket.
