I don't know Ben, I'm always using the latest stable releases of source packages 
which for fltk is 1.1.9. Don't know what is included in fltk-aqua? I would say 
that if the test programs glpuzzle and gl_overlay display something then you 
might have a good chance that the one as well as the other package can be taken. 
I hope this helps,
