I suspect your problem is that the 3.2.3 binary available at Octave Forge was 
made when Mac OS X defaulted to 32 bit compiles. With Snow Leopard the default 
is 64 bits. Therefore, with any package that includes source to be compiled, 
your mkoctfile has to be modified to force 32 bit compiles.

You will find mkoctfile at:

/Applications/Octave.app/Contents/Resources/bin/mkoctfile

assuming octave.app is installed in your system applications folder.

 For your convenience, I've attached a copy of my modified mkoctfile.

mkoctfile
Description: Binary data

If you want to try this out without modifying or replacing your existing 
mkoctfile, you can place it in a folder in your octave path. (Enter help 
addpath and help savepath to see how to put a folder in your path.)
