Hi Ole (with CC to Hez because of the OCaml issues):

The Intel 32- and 64-bit platforms are obviously the most important
hardware platforms to get right so that is very encouraging news
indeed.

I don't have the OCaml expertise to help you decide whether this is a
PLplot bug or an OCaml bug.  But I suspect the latter because of
the build success of our ocaml binding on other platforms.

@Hez:
Got any ideas about this?

@Ole:
To introduce you, Hez was the primary developer of our ocaml binding and
examples.  However, he has not been contributing to PLplot recently so
if he does not respond to the above question, I suggest you simply turn
off all OCaml-related packages on the hardware platforms where those
are failing to build.

By the way, thanks for the reference to
<https://buildd.debian.org/status/package.php?p=plplot&suite=experimental>
that you sent later.  I haven't had a chance to look at it yet for any
non-OCaml issues, but if you spot any of those, let me know.

Alan
