 G'day :)

 I recently upgraded to 10.7 (on Intel), so realised (after trying port
 selfupdate and it telling me it couldn't install macports 2.0.1 because
 the compiler didn't work) that I needed to follow the MacPorts migration
 instructions, as I had on previous OSX upgrades but blissfully forgot in
 between. After saving my port list, which was brief (30 items) as I had
 completely reinstalled the system fairly recently, I followed these steps.

 '''Step 1'''
 uninstall all ports:
 {{{
 sudo port -f uninstall --follow-dependents installed
 }}}

 Most of my ports reported an infinite loop. When I uninstalled each of
 these separately, I found the loop occurred because somehow they depended
 on themselves, e.g.


 {{{
 sudo port -f uninstall py26-crypto
 --->  Unable to uninstall/deactivate py26-crypto @2.3_0, the following
 ports depend on it:
 --->    py26-crypto @2.3_0
 }}}


 Self-assurance is one thing, but dizzy introspection is quite another.
 Fortunately, the individual uninstall forced the package-uninstall anyway.
 A few of the ports uninstalled normally in between, as I alternated
 "uninstall everything" with "just uninstall this one, and I don't want to
 hear about your psychiatric difficulties". So at this stage, I assumed
 uninstalling had sorta succeeded.

 '''Step 2'''
 clean all partial builds:
 {{{
 sudo port clean all
 }}}

 This started off well, but bugged out part-way through the letter A (A is
 for Angst when Migrating):


 {{{
 --->  Cleaning argus-monitor
 --->  Cleaning argyll
 --->  Cleaning aria2
 Error: Unable to open port: invalid command name "get_canonical_archflags"
 To report a bug, see <http://guide.macports.org/#project.tickets>
 }}}


 I couldn't find this error message anywhere when searching, so here I am
 dumping my problem in your lap. Sorry about that. I'm too sick to debug
 properly anymore.

 The migration process also requires upgrading to Xcode 4, but I don't have
 enough quota left, so will have to wait for a couple of days until my plan
 rolls over. (It doesn't wiggle its paws in the air, it just rolls over
 once a month.) The migration instructions did not specify upgrading Xcode
 prior to uninstalling.

 I'm going to look for a way to wipe macports and start again (being short
 of brain nowadays, I usually resort to the scorched-earth policy when
 confused), and hopefully that will make it possible to reinstall MacPorts.

 Meanwhile, here is the issue. Good luck, and I wish I could help. :)
