Nice, ...
notice that 3.05 is still in unstable :((( but 3.04 is in testing, so it
is not that catastrophic.
3.06 failed to build on alpha due to an out of memory message when
running the ocamldoc sh script. i hope this is only a problem with the
alpha box, and not a problem with ocaml, i will try to build it manually
nextly.

Please reread section 8) of the ocaml_packaging_policy :
Please reread section 8) of the ocaml_packaging_policy :
The ocaml libraries should always depend on the exact version of ocaml
they were build with. Since ocaml 3.06-1, the ocaml and ocaml-base
package now provide virtual packages called ocaml-3.06 and
they were build with. Since ocaml 3.06-1, the ocaml and ocaml-base
package now provide virtual packages called ocaml-3.06 and
ocaml-base-3.06 respectively.
Ocaml libraries should build depend on ocaml-3.06 :
Build-Depends: ocaml-3.06
Ocaml library runtime packages (the libxxx-ocaml)
should depend on ocaml-base-3.06 :
Depends: ocaml-base-3.06
And Ocaml library developpment packages (the libxxx-ocaml-dev)
should depend on ocaml-base-3.06 :
Depends: ocaml-3.06
Notice how it speak only about _library_ packages, not about application
packages, as it did as well in the older packaging policy, altough it
may have been less clear.
So, again, people don't really read what i write, maybe i am not clear
enough, should i be insisting more heavily on the fact that it only
concerns libraries and not apps here ?
Notice also, upstream does recommend to rebuild _everything_ when a new
release of ocaml is available, and the it is absolutely necessary to
build libraries with the exact same version of ocaml as the tools will
be built with, it may not seem so, but it is. As an example, when i
built my program with ocaml 3.05 and 3.04 built libraries (lablgl and
lablgtk) it seemed to work fine, but segfaulted when building on of the
files. Also notice that 3.05 failed to bump the .cmi version number,
thing which 3.06 did (xavier told me, i have not checked), and should
not even work with older 3.04 libraries anymore.
