I tried to check the package and I do not really understand in how far
the symlinks in r-cran-dt are wrong.  I've triggered salsa-ci
pipeline[1] which did not found the issue you mentioned above (can you
provide a link to the full build log?)

I'd be happy if you could provide a single example for a
debian/maintscript entry that would be needed to fix the issue
according to your opinion to make me understand better.

Kind regards and thanks a lot for your QA work

    Andreas.
