In general, we should be setting PREFIX to $out (i.e. /gnu/store/...),
and leaving DESTDIR unset.  Conventionally, these two variables have
different meanings: PREFIX is where the files are expected to be when
the code is run.  DESTDIR is meant as a temporary staging area when
building a package, with the expectation that it will be packed up into
a binary package and later extracted into PREFIX.  So, with this in
mind:

I think that this should be (string-append "PREFIX=" out) and DESTDIR
should be left unset.

I haven't looked at the details of this package, or tried to build it,
but I'd like to see a solution that follows the conventions above, if
possible.  Would you be willing to try this?

Thanks for your efforts!
