Comment (by RobK88):

 Thanks Ryan for the explanation.  I do hope that the `+universal` variant
 for `expat` gets fixed.

 Yes, the build error is completely different.  But I am a little confused.
 The `gdal` port already uses the `legacy-support` portgroup. It looks like
 another fix will be needed.
