Ahh.  Well, someone will have to probably come along and RPM-ize my
stuff later when it is ready, then, or I'll have to spend a lot of time
reading or something.  I only know how to work with Debian packages at
present; I think that the Debian system for building packages is
(mostly) intuitive, though I think it could be better...

So those files are in the root, or do you put them in the debian/
directory like you would in a Debian source package?

Would that be that silly -fPIC?

I am guessing that it doesn't use a simple Makefile like Debian's
"rules" does, then?  Is it a DSL or shell type thing or something?
