[Nix-dev] PERL5LIB and lib.makePerlPath

[Daniel Hlynskyi]

So, I found a hackish solution. Just create a new derivation with PERL5LIB
as it's output

# perl5lib.nix
packages:
  let pkgs = import <nixpkgs> {};
in builtins.readFile (builtins.toString (pkgs.stdenv.mkDerivation {
  name = "PERL5LIB";
  buildInputs = [pkgs.perl] ++ packages;
  buildCommand = "echo $PERL5LIB > $out";
}))

$ nix-instantiate --read-write-mode --eval -E 'with import <nixpkgs>{};
(import ./perl5lib.nix) [perlPackages.DBDPg]'
"/nix/store/...-perl-5.22.1/lib/perl5/site_perl:/nix/store/...-perl-DBD-Pg-3.5.3/lib/perl5/site_perl:/nix/store/...-perl-DBI-1.634/lib/perl5/site_perl\n"

It looks to me I'm reinventing a wheel...
