Some plugins might want to store system wide defaults in the same
sysconfdir as gaim. Now they can use this to detect how gaim was configured:
pkg-config --variable=sysconfdir gaim
printf("\n*** 'audiofile-config--version' returned %d.%d.%d, but the minimum version\n", $audiofile_major_version, $audiofile_minor_version, $audiofile_micro_version);
printf("*** of the Audio File Library required is %d.%d.%d. If audiofile-config is correct, then it is\n", major, minor, micro);
printf("*** best to upgrade to the required version.\n");
printf("*** If audiofile-config was wrong, set the environment variable AUDIOFILE_CONFIG\n");
printf("*** to point to the correct copy of audiofile-config, and remove the file\n");
printf("*** config.cache before re-running configure\n");
