Rebuild of Octave-3.6.4 lost the use of ARPACK eigs

[lascott]

Possibly broken symlink? Thoughts appreciated.

I rebuild octave after a panic crash left me without eigs:

a = rand(4000, 4000);
octave:11> tic, det(a*inv(a)), toc
ans = Inf  % should be 1, known problem solved in next release.
Elapsed time is 9.6492 seconds.  % Using ATLAS on 4 cores as seen on sys
monitor 

tic, eigs(a,7), toc
error: eigs: not available in this version of Octave

help eigs
'eigs' is a function from the file
/usr/local/octave-3.6.4/lib/octave/3.6.4/oct/x86_64-unknown-linux-gnu/eigs.oct

 -- Loadable Function: D = eigs (A)
 -- Loadable Function: D = eigs (A, K)
 -- Loadable Function: D = eigs (A, K, SIGMA) 
 -- Loadable Function: D = eigs (A, K, SIGMA, OPTS)   ....

     This function is based on the ARPACK package, written by R.
     Lehoucq, K. Maschhoff, D. Sorensen, and C. Yang.  For more
     information see `http://www.caam.rice.edu/software/ARPACK/'.

So the help is there, and it compiled as shown below:

/usr/local
