The simh makefile explicitly attempts to avoid dependent packages that users 
build locally on their own.  The goal is to get users to use OS vendor provided
packages.  The point here is that when the OS (or other parties) build specific
packages, those package builds are well tested and somewhat professionally
maintained.  When a user builds a package locally, they may or may not do it 
right and when they have problems I don't want to hear about them.

If someone, like Paul, really wants to locally build some package for reasons 
beyond the needs of simh, they certainly can, and when they do that, they 
also get to personally coerce simh to use it.
