I have two poudriere jails I use to create package sets for some
machines of mine, one builds packages with the X11 option, the other
without (using OPTIONS_UNSET+=X11 among other options, which ensures all
packages will get the same option, unless overridden per package, which
I'm not doing in this case).

I've just started those two from scratch for a verification, the one
without X11 just completed successfully building ocaml with correct
pkgname (with -nox11 suffix) and successfully build unison-nox11. I'll
also test these packages at runtime later just to be sure, but I'm
confident they are working correctly.

But looking at the old logs I see no indication of these problems. I
have an explanation for both cases, I'll check them, but it requires
time for poudriere runs.

Not exactly. Let's see (anyone correct me if I'm wrong in the explanation):

with the port as it was, like this(trimmed):

BUILD_DEPENDS+=        ocamlc:${PORTSDIR}/lang/ocaml
BUILD_DEPENDS+=        ocamlc:${PORTSDIR}/lang/ocaml-nox11

poudriere will see the port with a variable origin, depending on the X11
option. If in the same poudriere run there is any other port which
depends on ocaml, but with a different origin (which is quite possible,
maybe some other port without an X11 option, which unconditionally
depends on ${PORTSDIR}/lang/ocaml) poudriere will notice this and report
conflicting origins.

This is the problem jlh was seeing. I never noticed it since ocaml is
the only port depending on ocaml I ever build.

The only solution to this one is not having a variable origin.

Changing that to a fixed DEPENDS as the port is now, poudriere will look
into the ocaml port to discover it's pkg name, the x11 suffix for the
pkg filename isn't derived from the depends, but from the depended port
Makefile, so poudriere should in fact try to build the ocaml port with
the required pkgname automatically, named depending on the X11 option.

This leads me to think there is some misalignment of the X11 option in
your setup, that's why I asked for the full log of the failed build, I
need to check the environment.

-nox11 as a suffix is quite common and compiled in defaults are a
documented use for PKGNAMESUFFIX, so I can't criticize that.

Anyway poudriere uses the port build system to create dependency lists
and it does look inside the port Makefiles. Again, I suspect you are
building ocaml with X11 enabled and unison with X11 disabled. I'm not
sure I know a correct way to make it work.

It will anyway generate a conflicting package set, since ocaml and
ocaml-nox11 conflict with each other.

Having a variable origin for a port isn't a solution... The generated
packages would anyway have conflicts between them, which is a
consequence of the problem jlh reported.

I'm doing some testing but if you could provide me the build log of the
failed unison build it would help.
