I'm building my first autoconf managed package.

However I can't find any simple examples anywhere of how to specify a required library, and find that library where it might be in various different places.

I've currently got:

AC_CHECK_LIB(['event'], ['event_init'])

but:

1. It doesn't find the version installed in /opt/local/lib
2. It doesn't complain if the library isn't actually found
3. I need to set the include path to /opt/local/include too

any help, or links to decent tutorials much appreciated...
