Hi Richard:

Your messages are being rejected by the list for obvious reasons (no subscription),
but I do have access to them as list coordinator so I will answer (with
a copy to the list).

No, the above problem in version numbers was because Orion misidentified
the package which is camlidl and not ocaml.

The issue was with the camlidl command.  But according to Debian
packaging information that application depends on the ocaml-nox
package that "contains everything needed to develop OCaml applications".
Also, I have the following result:

irwin@merlin> file /usr/bin/camlidl 
/usr/bin/camlidl: a /usr/bin/ocamlrun script executable (binary data)

And ocamlrun is the OCaml byte-code interpreter.

So from your further result that everything works fine for the latest
git version of ocaml (where I assume you are still using the same
pre-release version of camlidl), it appears the issue is caused
(indirectly) by some Fedora inconsistency between their packaged
pre-released versions of camlidl and ocaml.

Anyhow, it appears the issue does not have a lot to do with PLplot (except as a platform
that exposes the issue).  So good luck solving it, and let me know how you progress.
