Xcode 2.4.1 is largely compatible, and fixes the Intel 64-bit issues 
that
makes using Xcode 2.2.1 not work for compiling some ports that want 
it...

Xcode 2.5, on the other hand, introduces some breaking changes so that 
it
can run in a prefix on Leopard - such as not including 
/usr/share/libtool:
