 Attached patch updates devel/caml-findlib to 1.2.4 as well as:
  - replaces distfiles & worksrcdir with just distname
  - points to new homepage and mirror site
  - removes unneeded extract.suffix
  - sets ocamlfind_destdir outside of post phases so it needs setting only
 once
  - uses destroot.keepdirs instead of manual turd file placement
