Can we upgrade or remove the zc.builout pin in:
http://dist.plone.org/versions/zopetoolkit-1-0-8-ztk-versions.cfg ?
It is specifying zc.buildout 1.7.1 which is old and has some nasty bugs that have since been fixed.
Overall specifying a build tool version in a toolkit kgs seems backwards - a case of tail wagging the dog.
+1 for upgrading to a more recent zc.buildout version.
zopetoolkit-1-0-8-ztk-versions.cfg is a copy a file from the ZopeToolKit (ZTK). Maybe it is better to override the requested zc.buildout version in the Plone versions file.
A discussion like this started 1 year ago in https://github.com/plone/Products.CMFPlone/issues/1502, asking why do we have different buildout versions across cfg files of same Plone milestones.
