die(), like print() and warn(), prints a list of strings. To do what I
think you are trying to do:

open my $FH, '<', 'somefile' or do {
# some statement here;
# and another statement;
# and finally;
die "some string here";

};

snip

There are at least three ways to do this. The way above is good if
this is something that needs to happen only on this error. If you
always want a piece of code to run when an error occurs you can
override the __DIE__ signal:

$SIG{__DIE__} = sub {
#do stuff like write to a log file
}

And if you need something to always run at the end of your program
(regardless if there was an error or not), you can use an END block:

END {
print "This will always run at the end of the program, regardless
of die() or exit()\n";
}
