I think the OP's basically stuffed ...

This is FUD. Didn't you notice I said (>4GB)?

Every version of Perl I've used on windows in the last 9+years has been built with USE_LARGE_FILES.

Here is perl processing a 12GB/141 million line file using Active State 5.10.1 in 88 seconds: 

C:\test>dir dna.txt
 Volume in drive C has no label.
 Volume Serial Number is 8C78-4B42

 Directory of C:\test

08/11/2010  16:35    12,831,000,000 dna.txt
               1 File(s) 12,831,000,000 bytes
               0 Dir(s)  281,938,862,080 bytes free

C:\test>perl -nE"}{say $." dna.txt

In the absence of evidence, opinion is indistinguishable from prejudice.
