You know thinking about it - the problem is in poudriere - or more of
the way it builds depends, and that could be the way the ports framework
thinks about things... and possibly pkg..
My thoughts about the fix would be to have poudriere pick up the options
when installing pre-built depends and specifically with the global
'unset' (which conflicts with the default 'set') have poudriere and/or
ports check for both ocaml and ocaml-noxll.... or on build pick up the
options of what is being depended upon... or remove the -nox11 suffix
completely (which would likely cause more issues.)
unison shouldn't care which version of ocaml is installed.. unless X11
is 'on' in which case ocaml needs to be compiled with X11 as well.
ocaml + unison = OK
ocaml-nox11 + unison = NOT OK
ocmal + unison-nox11 = OK
ocmal-nox11 + unison-nox11 = OK
Now poudriere sees the global and local X11 unset options when computing
deps and builds as specified in the options, but doesn't account for
unison-nox11 wanting ocaml-nox11 but ocaml is ok... The solution (if
possible) would seem to be tell unison that without X11 being set both
ocaml and ocaml-nox11 are valid dependencies and either are needed...
Of course that means the pkg manager needs to know this as well... which
neither pkg nor pkg_* can do.... though if in poudriere both can be
built so who cares? The solution then would seem to be to get unison to
request the dependency of ocaml-nox11 if X11 is unset in unison and
building in poudriere (can this be detected?).. or that the risk that
no-one would be stupid to ocaml-nox11 + unison (which a conflict of
ocaml-nox11* should solve) and therefore just test for ocaml is
installed by filesystem test and not via pkg test when building without
X11.... which would seem to be the solution to all of the above....
unless I'm missing something. The other solution for may just be to
patch the ocaml Makefile from:
OPTIONS_DEFAULT=X11 TK THREADS
OPTIONS_DEFAULT?=X11 TK THREADS
Which if I understand the param correctly will change from always set
the defaults to X11 TK THREADS to set the defaults if there is no
