[Aleksander Morgado <aleksm src gnome org>]

commit 65d7f0ac57421c4b043facead29de45cc65587a3
Author: Aleksander Morgado <aleksander lanedo com>
Date:   Mon Apr 12 20:01:03 2010 +0200

    Fixes GB#615563 - Proper handling of --enable-evolution-miner configure option
    
    * Put together all evolution-plugin stuff in configure.ac
    * Removed AC_DEFINE of HAVE_EVOLUTION_PLUGIN, as nowhere used
    * Enabled auto mode by default in --enable-evolution-miner
    * Merged USING_EVOLUTION_MINER and HAVE_EVOLUTION_PLUGIN AM_CONDITIONALs into
        a single USING_EVOLUTION_MINER
    * Issue configure error when --enable-evolution-miner=yes and evolution
        dependencies are not installed
