I have no objection to you adding svn 1.6, but I'm curious why. I know
this request is beyond our documented norms, but it would be nice to
expand the comment in DESCR to note that 1.6 is not the
upstream-recommended version, explain why 1.6 is useful/necessary (is
there something wrong with 1.7? is this just for people in managed
environments who haven't decided to upgrade?),
Where I'm coming from is that I see pkgsrc as doing two things for
users: one is wrangling builds so that 'make package-install' is all it
takes, and the other is making choices about what version is in the best
interests of the broad user base.
In the subversion case, it took a while to figure out what the
recommendations are, but I found:
https://subversion.apache.org/docs/release-notes/
which says basically that 1.7 is current and 1.6 is security fix only.
