Although operator precedence will do the right thing in your code .. 

open my $FH_infile,  '<', "$in_file"  or die "Can't open $in_file";
open my $FH_outfile, '>', "$out_file" or die "Can't open $out_file";

I prefer the more explicit 
open ( my $FH_infile,  '<', "$in_file" ) or
  die "Can't open $in_file";
open ( my $FH_outfile, '>', "$out_file" ) or
  die "Can't open $out_file";

In addition, I do like to give myself as much information as possible by adding $! to error messages: 
open ( my $FH_infile,  '<', "$in_file" ) or
  die "Can't open $in_file: $!";
open ( my $FH_outfile, '>', "$out_file" ) or
  die "Can't open $out_file: $!";

Also, I wasn't aware of File::Basename .. that's pretty handy.
