I am using the tarball. I try to avoid the bleeding edge stuff because
it causes too many problems.

This is breaking older Mac builds:

    AM_SILENT_RULES

AM_SILENT_RULES is useless because Autotools ignores it, even in the
newest versions. It serves no practical purpose. Its even more useless
because it breaks a build:

    configure.ac:26: warning: macro `AM_SILENT_RULES' not found in library
    configure.ac:26: error: possibly undefined macro: AM_SILENT_RULES
        If this token and others are legitimate, please use m4_pattern_allow.
        See the Autoconf documentation.
    autoreconf: /usr/bin/autoconf failed with exit status: 1
    Failed to reconfigure IDN

To build the library I remove it with sed. I'm in the same boat if I
add m4_pattern_allow([AM_SILENT_RULES]).
