obsolete-1.0: uses replaced_by without checking for it

[jbrinchmann@…]

I'm on Yosemite (10.10.3) and was trying to upgrade my MacPorts installation. I followed the instructions at wiki:Migration. For the sudo port clean all command I ran into an error:

--->  Cleaning capstone
Error: Unable to open port: can't read "replaced_by": no such variable

I then ran the clean explicitly on all installed packages and that completed without problems.

When trying to run restore_ports.tcl, however, the result was a failure:

> sudo ./restore_ports.tcl myports.txt
can't read "replaced_by": no such variable
    while executing
"default long_description "This port has been replaced by ${replaced_by}.""

    invoked from within
"sort_ports $portList"
    invoked from within
"set operationList [sort_ports $portList]"
    (file "./restore_ports.tcl" line 285)

This was a bit too obscure an error for me.

The replaced_by keyword was added in MacPorts 1.8.0, released August 2009. The error message indicates you are running a version of MacPorts older than that. Before attempting to reinstall ports, you should upgrade to the latest version of MacPorts.

Actually, I caused this unintentionally with r137979. Should be fixed with r138000.
