1.8 selfupdate to 1.8.1 fails resulting in Tcl problems

[ben-macports@…]

After reinstalling Macports 1.8.0 after migrating from Leopard to Snow Leopard. I upgraded OS X from 10.6 --> 10.6.1. On 28 September 2009, I ran "sudo port selfupdate" to upgrade from 1.8.0 to the new 1.8.1 which resulted in the following error when running port:

~ benc$ port
dlopen(/Library/Tcl/macports1.0/MacPorts.dylib, 10): no suitable image found.  Did find:
	/Library/Tcl/macports1.0/MacPorts.dylib: mach-o, but wrong architecture
    while executing
"load /Library/Tcl/macports1.0/MacPorts.dylib"
    ("package ifneeded macports 1.0" script)
    invoked from within
"package require macports"
    (file "/opt/local/bin/port" line 39)

What is the result of the following?

$ lipo -info /Library/Tcl/macports1.0/MacPorts.dylib

Also

ls -l `which gcc`

$ lipo -info /Library/Tcl/macports1.0/MacPorts.dylib
