1st attempt to build failed. I found from the Xcode tools error log that the macgpsbabel folder had to be renamed gpsbabel and the root folder also had to be named gpsbabel. I renamed them and tried again. No errors were logged and a MacGPSbabel.app was created, complete with custon icon. However the "get info" showed it as v. 1.2.4beta07242004. I got an error launching it that said the application was "damaged or incomplete". I'm not a programmer, but given decent instructions for a "makefile" or a GUI like Xcode tools, I'll at least give it a try. Though Mr. Lee was a bit harsh, I too appreciated the version 1.2.5 download that was pre-compiled. Since presumably the developer has to do this anyway to test it, why not just post the compiled app and include the source separately or a link to it on the sourceforge site. It would make it a LOT easier on us non-programmers. I guess for now I'll stick to v.1.2.5 as it has worked OK the few times I've needed it.
