If you need a 64bit Fortran compiler ping me off list. (PathScale not 
iFort of course)  I was working with some extremely large code a few 
months ago and one of our engineers could probably polish up my patch 
and send out test binaries to anyone interested.  All we would ask for 
in this specific case is feedback.
