Comment(by andrew.long@…):

 Replying to [comment:2 ryandesign@…]:
 > You could try downloading the MacPorts 1.9.2 disk image for your OS
 version from our download page and installing it again. This will not
 affect your installed ports.

 That's worked fine. I must admit, I'd downloaded the update last night,
 and was prepared to re-install it and to re-download all my old ports, but
 I'm glad that they were preserved.

 Thanks and regards, Andy

 PS - Would it have been useful to tr to re-build the installation
 manually? where would I have had to start?
