If you goto XCode's preferences, you will see a "Downloads" tab.  You should see it now listed in there as an optional download.  Also, I think XCode will notify you on launch if it sees an older toolchain installed to /, so you were probably be told about this when you did step 2 anyways.

This is probably a bug with the dependent ports from a MacPorts angle, since we want the compiler the Portfile/base specifies used, not what 'apr-1-config --cc' returns.  Force reinstalling the ports caching paths to the toolchain allowed the remaining ports to be built.  Some variant of the migration upgrade steps is probably required to make sure nothing has /Developer paths stored away…
