Use of apostrophe as package separator was deprecated in Perl 5.37.9,
and will be removed in Perl 5.42.0.  You should change code that uses
Test::More::isn't() to use Test::More::isnt() as a replacement at t/tmpdir.t line 46

It seems to happen in this block:

195 # The 'natural and safe form' for UNIX (pwd may be setuid root)
196 sub _backtick_pwd {
197 
198     # Localize %ENV entries in a way that won't create new hash keys.
199     # Under AmigaOS we don't want to localize as it stops perl from
200     # finding 'sh' in the PATH.
201     my @localize = grep exists $ENV{$_}, qw(PATH IFS CDPATH ENV BASH_ENV) if $^O ne "amigaos";
202     local @ENV{@localize} if @localize;
203 
204     my $cwd = `$pwd_cmd`;
205     # Belt-and-suspenders in case someone said "undef $/".
206     local $/ = "\n";
207     # `pwd` may fail e.g. if the disk is full
208     chomp($cwd) if defined $cwd;
209     $cwd;
210 }

Does Perl 5.38 assume a backtick is inappropriately used for an apostrophe?

The test seem to fail because the portpreviously was not installed. Now that it is the test starts – but FAILs.

This is surely an invalid report.
