I agree it is tiresome not to get all those error messages at once, and 
therefore I always try to write my configure.ac so configure doesn't 
exit when a package is missing but just collect that information and 
keep on searching for the other packages. And then in the end (just 
before AC_OUTPUT) I print out the missing packages and exit. There is 
nothing in current Autoconf that prevents you from doing so and if you 
use third-party macros that AC_MSG_ERROR on failure, you should really 
ask the maintainer of that macro to provide a MACRO([ACTION-IF-FOUND], 
[ACTION-IF-NOT-FOUND]) interface.

Cheers,
Peter
