[Nix-dev] How are perl modules handled?

My guess:
because it does not have buildInputs or propagatedBuildInputs.
Thus no $out/.. is written

No perl package references the perl interpreter which was used to
"build" ?! a store path. I'm not even sure you should call it build here
because in most cases it will be a "copy .pl files to $out" only and
some testing.

The missing piece is /etc/bashrc or such which defines PERL5LIB for your
user profile (and the system profile)
