What you are saying amounts more or less to basing GODI on the debian
packaging system. Interfacing between packaging systems is going to be
just as difficult as interfacing between GC's: almost impossible if
you are not a guru of the two systems. And then why not do it for all
other packaging systems around (rpm, portage, freebsd packages...)

I think that it would be much more reasonable to have a packaging
system controlling all of ocaml, but only ocaml. This includes
compiling and installing from CVS, because those are the cases when a
recompiling package system is really necessary, and because many
developpers (and potential contributors to GODI) are using CVS
versions of ocaml.

The interface to external packaging systems could be just minimal:
external packaging systems handle non-ocaml dependencies, and issue
GODI commands for installing/uninstalling the package. Since GODI may
have to recompile things later, having an external packaging system
trying to track GODI files would be a pain, and probably a useless
one.

This also makes me think that godi should not handle non-ocaml
packages (like gdbm currently), because this is only going to generate
frictions with other packaging systems.

Last, we need support for windows, and for binary packages. I don't
know who is going to do it, but these are requirements to make godi
the standard.

And of course, lots of maintenance needed. I must be using exotic
architectures, but godi never worked properly on any of my machines
(solaris8/x86  and freebsd5.2), at least without lots of tweaking.
Making it work properly on a lot of platforms will require a huge
amount of work, and cannot be handled by a single developper.
Which creates another problem: GODI is based on C tools and BSD
makefiles. I'm not sure this is the favorite kind of things ocaml
programmers would maintain.

By the way I'm ready to help, if there is some understandable way to
do so.
