ExifTool 11.50 won’t launch on macOS

[bdesham]

Issue description

I just upgraded nixpkgs.perlPackages.ImageExifTool from 11.49 to 11.50. When I try to run it I get this error:

$ exiftool --version
zsh: /Users/bdesham/.nix-profile/bin/exiftool: bad interpreter: /nix/store/h400cvgl5nd2a2sq6qlzzxxs26dqpj7g-perl-5.28.2/bin/perl -w -I/nix/store/h400cvgl5nd2a2sq6qlzzxxs26dqpj7g-perl-5.28.2/: exec format error

If I try from bash (which is not my usual shell and which isn’t set up for Nix), the message is even more gruesome:

bash-3.2$ ~/.nix-profile/bin/exiftool --version
/Users/bdesham/.nix-profile/bin/exiftool: line 12: use: command not found
/Users/bdesham/.nix-profile/bin/exiftool: line 13: require: command not found

/Users/bdesham/.nix-profile/bin/exiftool: line 21: `    $exeDir = ($0 =~ /(.*)[\\\/]/) ? $1 : '.';'

If I roll back to version 11.49 the command works fine from zsh and from bash. Version 11.50 works fine for me on an Ubuntu 16.04.6 system.

Fun fact: I was the one who broke this 😳 I had tested it successfully on a different macOS system, one running Mojave. The failing system is High Sierra (10.13.6). I will try to see if I can fix this but I thought I should report the problem ASAP.

Steps to reproduce

1. nix-env -iA nixpkgs.perlPackages.ImageExifTool
2. exiftool --help

This looks related to #2146, #35353, and #11133

[bdesham]

I believe this is specifically an instance of #35353 (the shebang line is too long for macOS), not #2146 or #11133 (shebang lines can’t point to interpreted scripts on macOS).

The shebang line I’m getting is

#!/nix/store/kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/bin/perl -w -I/nix/store/                     kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/lib/perl5/site_perl -I/nix/store/                          kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/lib/perl5/site_perl -I/nix/store/                          kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/lib/perl5/site_perl -I/nix/store/                          kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/lib/perl5/site_perl -I/nix/store/                          kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/lib/perl5/site_perl -I/nix/store/                          a5m191w2rd87nki7plk8ja9kl5hr5f2i-perl5.28.2-Image-ExifTool-11.50/lib/perl5/site_perl

which is 558 characters. The interpreter, /nix/store/kdhrydba180yvgwifsvqc4my23lgkjip-perl-5.28.2/bin/perl, is a binary.
