Mouse works for me with on linux x86_64 and i686 with fairly recent
gnuplot cvs though.
On i686 after fixing lapack/atlas issues I am still getting 1 failure
on make check:

 ***** testif HAVE_ARPACK
 [u2,s2,v2,flag] = svds(a,k,0);
 s2 = diag(s2);
 assert(flag,!1);
 assert(s(k:-1:1), s2, 1e-10);
!!!!! test failed
assert (s (k:-1:1),s2,1e-10) expected
   38.060
   38.060
   38.034
   38.034
   38.015
   38.015
   38.004
but got
   38.060
   38.034
   38.034
   38.015
   38.015
   38.004
   38.004

========

So I suspect that there are some problem with lapack left.
(Or may be with arpack.)

I am tempted to recompile everything with either "-ffloat-store" or
"-msse -mfmath=sse2" ...

Any hints would be appreciated.

Sincerely,

Dmitri.
