Interesting bit here:


DATADIR gets expanded to PREFIX/share/PORTNAME.
--> DATADIR_REL gets expanded to share/PORTNAME.
DOCSDIR gets expanded to PREFIX/share/doc/PORTNAME.
--> DOCSDIR_REL gets expanded to share/doc/PORTNAME.
EXAMPLESDIR gets expanded to PREFIX/share/examples/PORTNAME.
--> EXAMPLESDIR_REL gets expanded to share/examples/PORTNAME.
