too big to eat?

[Hao Zhou]

I was trying to open a text file which size is 2817663929 bytes and got
this message:

IOError: [Errno 79] Value too large for defined data type:

The machine is a Solaris 2.7 unix box with a few G memory and Python 1.5.2b2 
has been compiled with large file support options.

Is there any switch I can turn on to let Python chew the file?

Thanks.
Hao
