Unfortunately, I don't have 64-bit hardware so i can't test this, but if 
the ACML blas library is called libblas.so and is binary compatible with 
the reference blas, you should be able to just replace the system blas 
with the new one and octave would pick it up. The x86_64 version of 
octave in Fedora Extras is already compiled with --enable-64. Right now 
the blas and atlas packages provide blas libraries that are 
interchangeable. If only blas is installed, (/usr/lib64/libblas.so.3), 
octave will link to that at run time, but if atlas is installed 
(/usr/lib64/atlas/libblas.so.3) octave will link to that instead, even 
if the reference blas library is installed. You may be able to do 
something similar with ACML, (put it in /usr/lib64/acml/libblas.so.??, 
and put something in /etc/ld.so.conf.d/ like the octave-x86_64.conf or 
atlas.conf files) but I really don't know anything about whether it is 
actually binary compatible, and unfortunately I can't help with the 
compile problems.
