I thought this was on his TODO list or at least his wishlist from our last

No, i was wronghere, sorry, ...
i remembver now, what we agreed upon is :
Packages that use findlib will need to have findlib as Build-depend. It is
needed to build the library, not to actually use it.
All other Packages will register themself with findlib, either with the
ocamlfind program (if they build-depend on findlib already) or some shell
script doing this work, or some other stuff.
The only solution for doing packages that depend on findlib without findlib,
would be if findlib was able to pre-process the Makefile and produce a findlib
free Makefile. This is much similar in the way the auto-configure/auto_make
stuff is handled.
It is a upstream TODO item though, so in the meantime just use findlib for the
libraries that need them. libraries that don't use findlib will not be built
with it, but still register themselves with findlib. (in a way similar to the
emacsen stuff, see Ralf's patch to the ocaml package for detail).

No problem, i just wish everything will be tidied up before the freeze ...
