That should put together all the stuff to do it, but it isn't an
installable package.
Were it tweaked around to be one, then it ought to be what I am suggesting.
Then it becomes a matter of how to test for its existence and version, with, for
example, my play time toy requiring a version not more than 5 years old or so.

A "standard config" for a particular environment is going to use a particular
compiler.  If a package builder wants a different compiler, it would mean
that the builder would want to use a different .pc file.  Remember, this is
targeted toward folks that want a vanilla install on their current platform,
and don't want to spend more time configuring than compiling projects.
"Vanilla" would imply "vanilla compiler for this site" also.

You could even combine two "libposix" installs via some ``diff -Dname''
magic on the output text files.  (A hand wave -- I'm sure there are more
details.)
