[Zope] LARGE FILE SUPPORT

I'm using Zope with python and i'm having problems due to my Data.fs file is over 2GB. According to Python's Library Reference 8.1.1 I have to re-compile python with this sentence: CC="-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64" export CC ./configure 1- I'm using Red HAt Linux 6.2 How do I know if it's large-file-capable ? 2- How do I re-compile python as described in 8.1.1, there's any step-by-step guide ? Thanks Alejandro Singer
