It works for me (once I've fixed the errors in your posted code):

use strict;
use warnings;

use Math::BigInt;   # Missing from your posted code

my $x_dec = Math::BigInt->from_hex("0x000102030405060708090a0b0c0d0e0f
+");

print $x_dec, "\n"; # Not $x, as in your posted code

# Output:
5233100606242806050955395731361295
