To be clear, I would first try patching the Makefile by deleting all the system header dependencies from the Makefile and then see if Macports will build the project. But make sure the Makefile lists the location of all the directories where the header files
are located. (I typically place them in $(INCLUDES)). And make sure the rules contain $(INCLUDES).</div>

I agree with Josh, these headers look like they were automatically generated using something like "make depends". </div>

When creating a Makefile, it is GOOD practice to include these lines as it will ensure that the Project will rebuild the correct files when a header file was changed. Since it is a REAL pain to create them manually. Many developers use something like "make
depends".</div>

If there is a "depends:" target in the Makefile, you could patch the Makefile and add "depends" as the first Phony target to the "all:" target. e.g. </div>

Alternatively, you could try just patching the Makefile by removing all these lines (and any other line where a system header is the ONLY dependency in the rule).
<b>The vast majority of time, they are NOT needed to build the initial project.</b> (They are needed if you want to use "make" to rebuild your project properly on subsequent runs where the developer has changed one of more of these system header files. This
is not a normal scenario if one is using Macports to build the project).</div>
