The package now depends on devel/ocaml-ppxlib instead of on its
constituent parts. There have also been some minor improvements from
version 0.9 to 0.10.
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
