------------------------+--------------------------------
 After upgrading tiff from @3.9.7_0+universal to @4.0.3_0+universal, trying
 to upgrade iulib to @0.4-d9b9406fac75_4 fails during the build stage. The
 build log (also attached) contains the following relevant error:
 {{{

 config.log also has relevant info:

 As mentioned in the log, no `TIFFHeader` is defined in tiff.h for @4.0.3.
 Instead, we have `TIFFHeaderCommon`, `TIFFHeaderClassic` and
 `TIFFHeaderBig`.  tiff.h for @3.9.7 defines `TIFFHeader`, with fields
 corresponding to `TIFFHeaderClassic` in 4.0.3. Looks like iulib
 @0.4-d9b9406fac75_4 is incompatible with tiff 4. Is this something that
 the iulib devs need to handle, or can anything be done for macports?
