I made the change specifically in response to a user who was confused  
when Xcode 2 did not work with Leopard, because he couldn't find a  
newer version on Apple's site:

http://lists.macosforge.org/pipermail/macports-users/2008-August/ 
011312.html

He went to ADC: Downloads: Mac OS X. The latest version I find there  
is 2.2.1.

Now, you and I know to go to ADC: Downloads: Developer Tools instead,  
which is where all versions of the Developer Tools (except Xcode 2.0)  
are located, going back to the December 2002 Developer Tools for  
Jaguar before it was even called Xcode. But if a user doesn't know  
that Xcode 2.2.1 isn't the latest, they won't go looking for a newer  
one.

I don't like the "Download Latest Xcode" button because it only gives  
you the latest Xcode for Leopard; it doesn't give you the latest  
Xcode for Tiger or Panther. I do want to continue supporting Panther  
as much as possible. I know we have at least one active Panther user  
on the list. I see no reason to cut off support for Panther at this  
time.

I agree "as of this writing" isn't good without a date, and that I  
shouldn't have created the situation where we have to update the  
Guide with "latest" information about Xcode releases, even if they  
are infrequent. Instead, how about we list a minimum Xcode version?  
The minimum supported Xcode version for MacPorts is 3.0 on Leopard,  
2.4 on Tiger and 1.5 on Panther, as seen in the MacPorts configure  
script:


case "$XCODE_VERSION" in
   1.[[0-1]]*|2.[[0-1]]*)
     AC_WARN(This version of Xcode Tools is not supported)
     AC_WARN(Please upgrade at http://connect.apple.com/)
     ;;
   1.[[2-4]]*|2.[[2-3]]*)
     AC_WARN(This version of Xcode Tools is out of date)
     AC_WARN(Please consider upgrading as some ports fail compiling)
     ;;
   1.5*|2.4*|3.*)
     dnl Supported version
     ;;
   *)
     ;;

How about this text?


         <para>Install the latest version of Xcode Tools. The minimum  
versions
         which are supported for use with MacPorts are Xcode 3.0 on  
Mac OS X
         10.5 Leopard, Xcode 2.4 on Mac OS X 10.4 Tiger, and Xcode  
1.5 on
         Mac OS X 10.3 Panther. If your Mac OS X install disc has an  
earlier
         version of Xcode Tools, don't use it—older versions of Xcode  
Tools
         often cause port install failures. Instead, download the  
latest version
         from <ulink url="http://connect.apple.com/">Apple Developer
         Connection</ulink> &gt; Downloads &gt; Developer Tools.</para>
