You should not need -loctinterp.

It is easier to do this if you are not using shared libraries.  The
problem is that there are modules in liboctave that depend on the
readline and kpathsearch libraries, but the versions used by Octave
are not installed by default.

I'd like to resolve this problem and make it easier to use liboctave
separately from Octave, but it is a relatively low priority project
for me.  Would anyone like to help?  If so, please contact me.

Thanks,
