Looks to me like font selection in lualatex is the problem. I don't
have access to a system with the pretest till Monday but I'd guess
that if you tried

\usepackage{libertine}

everything would work; libertine.sty uses font selection by file
name rather than font name. And you should get the same output with
pdflatex or latex->dvips->ps2pdf.
