NEW SIMPLE EXAMPLE

I'm updating this node with a very simple test case that demonstrates the problem and does not require Mojolicious: 
# works in plain perl
# fails with this compilation line:
# pp -P -r -v 99 -o packed.pl  somefile.pl

BEGIN {
    use File::Spec;
    for (@INC) {
        if ( !ref $_ && -d $_ && !File::Spec->file_name_is_absolute($_
+) ) {
            $_ = File::Spec->rel2abs($_);
        }
    }
}

sub hello {
    my $file = __FILE__;
    warn "My file name is $file. Here is my contents:";
    open(my $fh, "<", $file);
    my @data = <$fh>;
    warn "@data";
}

hello();

1;

OLD NODE

With the latest Mojolicious from CPAN, if you use PAR::Packer to create an executable for webapp.pl by running pack.pl (by cloning this repo) then Mojolicious::Controller will fail to find the template directory because it uses this code to do so: 
my $T = File::Spec->catdir(File::Basename::dirname(__FILE__), 'templat
+es');

[download]
Because PAR::Packer-based executables run out of a temp directory, the relative path returned by __FILE__ is not found. Changing line 21 to 
my $T = File::Spec->catdir(File::Basename::dirname($INC{'Mojolicious/L
+ite.pm'} || __FILE__), 'templates');

[download]
results in the binary version of webapp.pl running successfully.

good questions, no answer yet

The author of Mojolicious asked a good question regarding my described symptoms:
18:18 <@sri> even if it's in a temporary directory why would __FILE__ return the wrong file?
