Yes, but i am still not convinced by it.
Maybe there is a legitimate reason for packages to provide empty
stublibs dir ? Maybe some library which does not provide stublibs by
itself, but can be used to generate some.
For example, ocaml-base provides /usr/local/lib/ocaml/3.06/stublibs,
but this directory is empty, and anyway i hardcoded it in
ocaml-ldconf.ml.
Anyway, having the libraries do the job for each of them sounds neater
to me than having ocaml-base do the cleanup for the mess broken
libraries may leave behind them.

Yes, this is an acceptable workaround, the idea of keeping track of the
version number was a sort of optimisation, so that if we know that the
currently installed library package is not broken, then we don't need to
cleanup /var/lib/ocaml/ld.conf. Especially as most libraries will not
need to touch any ld.conf file anyway, since they should put stublibs in
the default place (/usr/lib/ocaml/stublibs).
