Sorry, maybe I misunderstood what the problem was.  Looking at your
patch (duh, should have done that before I replied the first time) it
doesn't change the way .oct files are created, but does change the way
they are opened, correct?  If so, then yes, please try this and see if
it works to use the dlopen interface to open the .oct files that are
created with libtool.  If so, then yes, I think this change should be
applied.

Thanks, and sorry for the confusion...
