./configure LLVM_CONFIG=/bin/llvm_config_64
seems to work for me:

With octave 3.6.3

octave:8> tic; for ii=1:1e7; ii+1; endfor ; toc
Elapsed time is 8.7 seconds.

with current snapshot:


octave:4>  tic; for ii=1:1e7; ii+1; endfor ; toc
Elapsed time is 0.018554 seconds.


Though i do not see much difference with the Octave2 sciviews
benchamrk (http://www.sciviews.org/benchmark/index.html)
that does things like:

cumulate = 0; b = 0;
for i = 1:runs
  b = zeros(220, 220);
  tic;
    for j = 1:220
      for k = 1:220
        b(k,j) = abs(j - k) + 1;
      end
    end
  timing = toc;
  cumulate = cumulate + timing;
end

Dmitri.
