Error: Port render not found

[Artie Ziff]

Hello,

Thanks to Bryan for the *very* helpful user notes (reminders).
I had not resolved that Tiger => Leopard upgrade snafu until now.

>From that page I saw this command:

sudo port clean --work <list>

I used it as so:

sudo port clean --work installed

It upchucked this:

--->  Cleaning antlr
--->  Cleaning apache-ant
--->  Cleaning apache2
.
.
.
--->  Cleaning rb-rubygems
--->  Cleaning rb-sqlite3
--->  Cleaning rb-termios
--->  Cleaning readline
--->  Cleaning readline
Error: Port render not found


Just posting for perspective.
Is this a bug?
Or yet another config problem with my system?


Cheers!
Art
