 Yes, that file has been merged incorrectly by the muniversal portgroup.
 That is to say, the files built for the two architectures differed, and
 the muniversal portgroup tried to merge them using C preprocessor syntax,
 but the cmake file format does not accommodate such merging so the
 resulting file is syntactically invalid.

 I'm certain I have seen this in another ticket, and was surprised that the
 muniversal portgroup attempted this merging, and suggested that the fix
 should be that the muniversal portgroup would error out if it encountered
 differing cmake files, but I guess that wasn't done yet and I can't find
 that ticket now.

 I have filed a bug report with expat to see if they can remove the
 differences that led to the necessity to merge:
