Max file size problem on 32-bit

[Vimal George <vimal@canthack.net>]

Using the scrypt Proof-of-concept file encryption utility at http://www.tarsnap.com/scrypt/scrypt-1.1.4.tgz
I encrypted a 2.5 GB server backup tarball on a 64 bit linux server (Ubuntu Hardy LTS)

Upon attempting a 'scrypt dec' on the same downloaded encrypted file on a 32bit linux desktop (Ubuntu Hardy LTS),
i'm getting an error message as follows : 

scrypt dec backup2009-oct20.tar.crypt backup2009-oct20.tar

scrypt: Cannot open input file: backup2009-oct20.tar.crypt: Value too large for defined data type

I'm guessing this has something to do with some 2GB filesize addressability problem on 32bit platforms(just guessing from the google results).

Any quick hacks to make this decrypt work on a 32bit linux kernel?
or Do i have to boot a 64-bit linux image and re-build scrypt on the same to do this decrypt?
