Comment(by ryandesign@…):

 Port depending on itself is certainly a new failure to me. That... should
 not happen.

 `get_canonical_archflags` is one of the new commands introduced in
 MacPorts 2; MacPorts 1.x won't be able to understand ports containing that
 or the other new commands.

 The usual order of operations is:

  * Upgrade to Lion
  * Upgrade to the version of Xcode required by Lion (4.1+)
  * Upgrade to MacPorts 2.0.1
  * Follow [wiki:Migration] instructions (uninstall ports, reinstall them)
