Fine, then print a big honkin' warning. If MacPorts ever encounters  
an error during the configure or build phase of a port, have it print  
something like this at the end:


YOU ARE USING AN OUTDATED VERSION OF XCODE, AND THIS MAY HAVE CAUSED  
THE PROBLEM YOU JUST ENCOUNTERED. Please go to http:// 
developer.apple.com/ and download and install the latest version of  
Xcode. Then clean this port and try installing or upgrading it again.
