checking for DBUS... no
configure: error: Package requirements (dbus-1 >= 1.6) were not met:

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables DBUS_CFLAGS
and DBUS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
