Lion clean (from scratch) install, XCode 4.3 (4E109) + command-line tools and MacPorts-2.0.4-10.7-Lion - NO GO

[Stefan]

Clean (from scratch) installation of Lion (10.7.3), followed by XCode
4.3 (4E109), followed by Command Line Tools install via XCode
Preferences -> Downloads -> Components, followed by
MacPorts-2.0.4-10.7-Lion.dmg -> pkg install, leads to:

$ sudo port upgrade
Warning: xcodebuild exists but failed to execute
Can't map the URL 'file://.' to a port description file ("Could not
find Portfile in /Users/my-username").
Please verify that the directory and portfile syntax are correct.
To use the current port, you must be in a port's directory.

$ echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

$sudo su -
#  port upgrade
-sh: port: command not found

Any suggestions?
