 I imagine that there's a clean and elegant solution to this, but the hack I'm currently using is to have `./make` alter `ikiwki.in` before it's run, by inserting `use lib ...` lines for each of the directories in `$ENV{PERL5LIB}`. Again, this is clearly ugly, but it allows me to run `./make`, so I'm submitting it FWIW.
