Comment(by illogical1 at gmail.com):

 The Portfile will need to be modified for the correct ${prefix} directory
 and Documentation location to fit in properly w/ the macports environment.
 A reinplace line can fix the docs problem. I'm not so good w/ sed though.
 I, myself, wanted it to integrate w/ Xcode 2.5 on 10.4 so that's why I
 built it this way.
