#725: arpack problem on mac os x

Comment (by cdavid):
Ok, to see the problem, here is simple pure fortran program:
{{{
program main
complex X, Y, Z
complex cladiv
X = (1, 0)
Y = (0, 1)
Z = cladiv(X, Y)
print *, Z
end
}}}
cladiv computes X/Y, so it should shows something like (0, -1). To make it
work on Mac OS X with accelerate:
{{{
program main
complex X, Y, Z
X = (1, 0)
Y = (0, 1)
call cladiv(Z, X, Y)
end
}}}
I can't understand why Apple decided to keep the F77 LAPACK name for a
CLAPACK function. This means we have to modify ARPACK sources to make it
work, somehow.
