examples/Makefile.am: installing 'build-aux/depcomp'
libgsignon-glib/Makefile.am:1: error: Libtool library used but 'LIBTOOL' is undefined
libgsignon-glib/Makefile.am:1: The usual way to define 'LIBTOOL' is to add 'LT_INIT'
libgsignon-glib/Makefile.am:1: to 'configure.ac' and run 'aclocal' and 'autoconf' again.
libgsignon-glib/Makefile.am:1: If 'LT_INIT' is in 'configure.ac', make sure
libgsignon-glib/Makefile.am:1: its definition is in aclocal's search path.
pygobject/Makefile.am:2: installing 'build-aux/py-compile'
