I don't think this is the problem -- shebang lines are ignored in tests because they are invoked with a specific perl.

/usr/bin/env perl would not be correct in any instance, as that doesn't work on all distributions, and whenever a new perl process is invoked, $^X should be used.

For me, using perlbrew on perl 5.23.1 on darwin, I can run tests just fine, but not install:
