The part of the code you show here is good.

Is your perl compiled with large (that is >2Gb) file support?

You can tell by doing 

> perl -V:uselargefiles
uselargefiles='define';

If the output isn't uselargefiles='define'; you need to get or compile another perl binary. Uselargefiles is an option you need to set when compiling the perl interpreter, though the default in recent perls ( I believe since 5.8.0 ) is to turn it on.
