The modules of my web application are placed next to the executables in ../lib directory. I keep trying to use FindBin in order to add this directory to @INC but it does not seem to work in -Taint mode. 
#!/usr/bin/perl -T
use strict;
use warnings;

use FindBin;
use lib "$FindBin::Bin/../lib";


use CGI;
print CGI->new->header;

This dies with the famous "Insecure dependency in require while running with -T switch" error.

The following cleans up the taint but I am just playing with fire here, right? Should I really blindly trust FindBin? 

#!/usr/bin/perl -T
use strict;
use warnings;

use FindBin;
my $path;
BEGIN {
    if ($FindBin::Bin =~ /(.*)/) {
        $path = $1;
    }
}
use lib "$path/../lib";


use CGI;
print CGI->new->header;
