Comment(by david.hislop.1@…):

 Thanks, developer_dir was set in {{{$prefix/etc/macports/macports.conf}}}
 to {{{/Developer}}}, the location where Xcode 3.x was formerly installed.
 I uninstalled it after installing Xcode 4.3.1.

 I don't recall ever setting it myself, although perhaps I ran something
 when I installed MacPorts a couple of years ago.

 How does it get set (apart from editing {{{macports.conf}}}?)
