As far as lisp see here LISP programming in Haiku and OS development with lisp
Getting ECL working is probably the most straight forward.
It already has a reciple in Haikuporter not sure why it is not being built and packaged https://github.com/haikuports/haikuports/blob/bf5779343db785b3a1e3aeada09eedf65f745e87/dev-lisp/ecl/ecl-16.1.3.recipe
regardless that is probably where you want to start as it is helpful to already have a lisp when boostraping another lisp.
