     Does anyone have experience at compiling the code on this platform, and has
     any hints as to what i am doing wrong.


You're not doing anything wrong.  It's simply that your version of
yacc doesn't accept the -o flag.  If you install GNU Bison instead of
the traditional yacc, then this error should go away.

Having said that, this is a problem compiling the demo code.  If this
is the first error you've seen, then the library has been compiled
okay, and you should be ready to use it.  You need the demonstration programs
and tests only if a) you're a libann developer; or b) you're
suspicious about the library and don't believe that it actually works.

If you choose to compile and run all the demonstrations, then you will
also need a number of other tools; GNU Octave to name one.  Otherwise
you can go ahead and install the library.
