I want to init the gem path with the available gems, ruby does that
internally but there is no way to do that without either
invoking ruby_options() or do it manually. Before 1.9.3 I could just
add a prototype for Init_prelude and call it, but the
symbol is hidden completely now.

There is a ticket about which would really ease this whole thing:
