Fixing this properly seems like it would take effort indeed.

Am I correct in assuming that as a temporary (personal) workaround, I can
just
install ncurses in my profile as well?

Perhaps guix can warn if you install a package which has a dependency
with a search path like ncurses? Or would this be too much of a hassle
to implement?

It would not solve the issue, but at least prevent people from
not understanding why their packages are not working. WDYT?
