Absolutely the same things happen not only with pkg_rr but also
with binary package managers. In pkgtools/nih for resolving
this kind of issues I remove sometool-1.0 with a help of "pkg_delete -f".
This solves the problem but I'm not satisfied with this approach
because if something bad happens in the middle of update
I'll have broken pkgdb.
Also, I'd prefer not to run "pkg_admin rebuild" for restoring +REQUIRED_BY
in the end.
Another problem is that after "pkg_delete -f", flag "automatic" (pkg_add -A)
is lost as well as other custom flags (in nih I also use "keep" and "try_out"),
so I have to make some thing to restore them.
I think the real problem is in pkg_install. I'd prefer the
functionality in pkg_delete or pkg_admin like the following:
"Run uninstall script, remove all files that belong to the specified package,
remove files from pkgdb listed in +CONTENTS, and then remove all
CONFLICTS entries from pkgdb, but keep everything else".
This is not a final solution. This is the first thing that came to my mind.
Neither "pkg_admin delete" nor "pkg_admin unset" work as needed.
