But that (mechanism) assumes you know where libevent was installed
(which is a local policy choice).

So if the answer is "Let's produce a libevent-config program that is a
1-liner that does this" then that may be an OK answer.  It would require
pkg-config to be installed though, and I'm interested in this capabilty
for *portability*, and making folks install even more software is not
the way I'd like to see this evolve.

I don't know exactly what you mean by that, but it's where I was gonna
go next, as I also need autoconf macros to do some things with libevent
(like see if a local version exists, and is at a suitable version level.
If so, we can use the existing, installed libevent.  Otherwise, we
should configure, build, *possibly* install, but link against, libevents
that is included in the "parent" package).
