 I neglected to notice originally that this line shows that MacPorts is in
 ''/private''/opt/local instead of just /opt/local, presumably with /opt
 being a symlink to /private/opt. This could happen if you installed an
 ancient version of Cisco VPN. We had a FAQ entry for this problem, but
 removed it from the FAQ over 7 years ago because at that time it was
 already old news (Cisco had already fixed the problem in newer versions of
 their installer), but you can follow those instructions to set things
 right to put MacPorts back into /opt proper:

 wiki:FAQ?version=1#IjustinstalledMacPorts1.2fromthe.dmgandIseemtohavelostallmyinstalledportsakaCiscoVPNatemyMacPorts

 The reason this situation is now an actual problem is that recent versions
 of MacPorts have a bug when the configured prefix is a symlink. I can't
 find the ticket about that at the moment. It may already have been fixed
 in trunk (which will become MacPorts 2.3).
