Autoconf macros detect build requirements only.  For run-time requirements
you should have a configuration file or something like that.  (Consider
binary packages.  Imagine the packager builds your package with the latest
and greatest /home/me/src/gcc-current/bin/gcc3.99.  100% of the users
would be screwed if you use Autoconf to record this as a run-time
setting.)
