So, looking at this, I see that it needs (and bundles) libdes, which 
looks long dead upstream, and uses a static lib.  libdes isn't in 
Fedora, or Debian as far as I can tell, so we may have to bundle it. 
That makes me nervous, since if it's dead, it may have vulnerabilities 
that are going unpatched, which makes me additionally nervous if we then 
go on to package games that make use of this.

Thoughts?
