Comment (by jmailman@…):

 Thank you for this. Indeed I installed VPN client about three computers
 ago (about 10 years ago probably) and it must have migrated to each
 subsequent  computer I had.

 I can see in the Finder that I have an alias opt at the root, that points
 to another opt folder in my user directory.  Are you saying I just delete
 the alias, and move the opt folder in my user directory to the root level
 of the hard drive?

 If so, then what?  Should I again try      sudo port install libusb
 +universal

 Or do I do something else first?
 Thanks in advance.
