I think the RPATH is a thing of the elf format or whatever to find the path to
libraries, in the static case probably or something such, since usually ld.so
will handle that just fine.
it is set for all ocaml binaries, mostly because upstream ocaml does feel
paranoiac, and non-debian-ocaml-users can install ocaml in some random and
varied possible way with libraries installed all over the place.
It should thus never be needed for ocaml packages in debian, and there are
some which consider rpath evil even.
I would thus recomend that the 3.09.2 ocaml package applies the above patch
(after cheking its validity), and that maybe we start lobbying upstream to
include a -norpath or whatever option to configure to disable this rpath
stuff.
