If your application links to Octave at least part of it must be installed for 
your
application to work. If you don't want your users to install Octave themeselves
you have 2 options

1 - Build a static version of octave libs and link your application statically 
to them

2 - Distribute Octave libs together with your application

Both options are quite difficult, especially if you need to support multiple 
platforms.

You probably know already, but remember that being Octave GPLv3, if your 
application will
also need to have the same license.

Yes. I build Octave on OSX myself, but currently not with the standard OSX 
toolchain, 
I need to install a different compiler suite (GNU gcc 4.7)

Yes. But it currently does not seem to work correctly with the lapack library 
that ships on 
OSX by default (-framework Accelerate) so you need to install a different 
version, for example Atlas.
