sorry, it seems I pasted the link incorrectly the correct link is

http://wiki.octave.org/Enable_large_arrays:_Build_octave_such_that_it_can_use_arrays_larger_than_2Gb.

(with a "." at the end)

You mean this page in the manual, right?

http://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html#Compiling-Octave-with-64_002dbit-Indexing

If you cannot understand the instructions provided there, I think it is 
unlikely that you will be able to get "--enable-64" running yourself.

The question is, are you really sure you really need that?

Do you understand that Octave is built by default with 64bit pointers on a 
64bit system, and it can access more that 2Gb of memory
 while "--enable-64" is meant to enable 64bit integers so that you can index 
one single array whith more than 2^30 elements?

If you really understand what "--enable-64" does and you are positive that it 
is crucial for you to have this feature working
how much would you be willing to pay for someone to install a version of Octave 
with that feature on your system?
