Makefile.am:1: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:1: The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:1: to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:1:
Makefile.am:1: If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:1: its definition is in aclocal's search path.
Makefile.am:1:
Makefile.am:1: If you install Automake in its own prefix,
Makefile.am:1: you'll need to arrange for the Libtool m4 files
Makefile.am:1: to be found by aclocal. For info on this, see:
