I fully appreciate your plight as a package maintainer, but I think
that users which use rollouts, a quite important GNUBG feature, care a
*lot* about speed.
Perhaps the GNUBG code can be structured in a way that it can be
compiled with all those "advance features", yet they are used *only*
in rollouts and so everything else works on older systems?
Is that possible or am I just showing my ignorance?
