For Haunt’s own modules, you could set the right search path in the
‘haunt’ command itself, like the Shepherd and Guix do.

For these external dependencies, you could always use ‘search-path’ at
configure time to hard-wire their locations in ‘haunt’ as well.  (Guix
does not do that and I don’t know of any project that does, but IWBN.)
