It appears that this macro comes from the Autoconf archive rather than from Autoconf itself. The failure indicates that the macro definition was not provided and so no substitution occured. You likely need to provide the .m4 file containing this macro definition as part of the package since it might not be available installed on the system.
Google appears to be a wealth of information on this topic. Bob -- Bob Friesenhahn bfriesen@xxxxxxxxxxxxxxxxxxx, http://www.simplesystems.org/users/bfriesen/ GraphicsMagick Maintainer, http://www.GraphicsMagick.org/ Public Key, http://www.simplesystems.org/users/bfriesen/public-key.txt
