  Until one of the experts shows up, I'll post my (probably half-garbled and
incomplete mis-)understanding: it depends which of the libtool variables you
add -l and -L options to whether they get carried over into the dependencies
or not, but if I try to remember the exact rules I'll probably get it wrong.

  How do your liboctinterp_la_LDADD, liboctinterp_la_LDFLAGS and/or
liboctinterp_la_LIBS definitions look?  It's probably a matter of tweaking
what goes in which one.

    cheers,
      DaveK
