Presumably everything you need is open source, so you could cut and paste together your own package with minimal dependencies.

A big disadvantage in doing this is that it erects a large barrier to upgrades: if geneplotter changes, you'll have a hard time incorporating the changes.

In my opinion, you'd get better bang for the buck by buying some new hardware that does the same stuff faster, rather than spending the time to change the dependencies.
