 I have seen problem this before and thought it had been squashed in this
 port but it has appeared again.

 ARPACK has a problem in that it uses the BLAS routine ZDOTC which has a
 different calling convention in Accelerate.framework then that used by
 GFortran which causes crashes that I have encountered in my code.  I know
 that this was the source of the problem because when I downloaded arpack-
 ng and patched it manually, replacing

     X = ZDOTC(....)

 with

     call ZDOTC(X,...)

 then the problems went away.

 I am not sure how people would prefer to see this problem solved, but I
 could submit a patch making the changes above if you all would like.
