Hi !
I tried to add some add-ons to my buildout.cfg and then ran bin/buildout, I got this error
(myenv) imacfixs-MacBook-Air:zinstance imacfix$ sudo -u plone_buildout bin/buildout Password: The constraint, 2.2.5, is not consistent with the requirement, 'zc.buildout>=2.9.4'. While: Installing. Getting section lxml. Initializing section lxml. Installing recipe z3c.recipe.staticlxml. Error: Bad constraint 2.2.5 zc.buildout>=2.9.4
Any help please ?
I've changed the zc.buildout ans step tools versions then I got another error when running buildout 
Please help me fix this
Reading the last error in your image:
Error: Referenced option does not exist: buildout var-dir
Is saying that you didn't create a var-dir option in your [buildout] section.
Try to add:
[buildout]
var-dir = ${buildout:directory}/var
I got many warnings and in the end
This is exactly what I get

something seems very wrong here and you should fix that first, everything that follows can only go downhill after that.
Plone 5.1 has 4.4 version for zope.interface. Plone 4.3.17 has 3.6. There is something missing from your config that should limit the research on pypi to package versions compatibles with your elderly Plone version. I don't think Plone 4 can work well with shiny new Zope.
From a Plone 4.3 install, it seems that you should have something along the lines of
extends =
https://dist.plone.org/release/4.3.xxxx/versions.cfg
in your buildout with xxxx as your base config version.
you should post your config so that the buildout experts can take a look.
